Make sure to fully close Wallpaper Engine when updating. If you are having issues, try verifying the files over Steam first.

Hey all,

Another small update for Wallpaper Engine has been released that is focused on fixing some issues that have come up:

The web engine (CEF/Chromium) has been updated to the latest version. This should fix loading of certain web pages and some DPI scaling related issues (the web wallpaper not being fullscreen or not registering clicks). If you are still having these problems, please let me know. Automatic pausing when Microsoft Edge is fullscreen, i.e. playing a video, should be fixed too.

I replaced the shimmering particles wallpaper with a new dynamic version that allows color changing and is designed to support stretching over three monitors (resolution of 5760 x 1080).

The Windows color adjustment on Windows 10 can now additionally be configured to overwrite the Windows settings for title/task bar colors. You can choose to keep the current Windows settings or overwrite them.

The tag "multi-monitor optimized" is gone now, because it was almost exclusively being abused. A new tag was added, "Unspecified", which is the default genre. The tag input control has also been replaced with a simple drop down menu, to reduce tag abuse:

I also got in touch with EVGA about excluding Wallpaper Engine from EVGA Precision X so the crashing issues when both applications are running should be gone with their next update.

If everything goes as planned, the next update will finally introduce the playlist/random feature in about 2 to 3 weeks.


  • Fixed Traditional Chinese flag.
  • Potentially fixed Edge fullscreen not pausing videos.
  • Potentially fixed a audio recording crash if an application in exclusive mode is started.
  • Fixed web wallpaper not covering the entire monitor on some systems.
  • Fixed web wallpaper clicking on some systems (I hope).
  • Fixed certain web pages not loading by updating CEF.

  • Made Windows color adjustment work without overriding the taskbar/title bar color settings.
  • Made it possible for web wallpapers to read the application language from the 'language' property.
  • Replaced shimmering particles wallpaper with a dynamic scene that supports coloring and stretching over triple screens.
  • Added a warning message when the user attempts to play video on Windows N with missing video components (prompts to install the Media Feature Pack).
  • Changed tags input into a drop down.
  • Removed Multi-Monitor tag, add Unspecified tag.
  • Added a CEF file check that warns the user when Steam only partially updated the application (which leads to problems).

Hey all,

I've released a small patch that adds a notice about acceptable content for Workshop, full support for 64-bit during auto start and launching from Steam and a huge number of new translations. Thank you everyone who has helped with those!

This notice will be shown when you open the editor, to make it clearer what is accepted on Workshop and what isn't. These rules are pretty much the same for any Workshop on Steam. Workshops have to be suitable for minors, too, so nudity and violence is not allowed, while it is allowed on some games on Steam (which are then rated M or A).

You can now use the 64-bit version of Wallpaper Engine. To switch, close Wallpaper Engine and start it over Steam, while choosing the 64-bit version there. If you configure auto start with this version running, it will then also use the 64-bit version during auto start.

A bunch of new Workshop tags have been added, including "CGI, Cyberpunk, Landscape, Medieval, MMD, Pixel art, Relaxing, Retro". It is now also required to specify at least one tag when uploading your submission. I think most cases should be covered, but if you think there are some urgent tags missing, make sure to let me know. The tags in the editor also have translations now, next to the original English version shown on Workshop.

Full changelog:

  • Added support for 64 bit auto start and Steam launcher.
  • Added localization for Swedish.
  • Added localization for Traditional Chinese.
  • Added localization for Spanish.
  • Added localization for Lithuanian.
  • Added localization for Japanese.
  • Added localization for Thai.
  • Added localization for Czech.
  • Added localization for French.
  • Added localization for Korean.
  • Added localization for Finnish.
  • Added a warning if run on a system that falls below the minimum OS requirements.
  • Added a modal to the editor that informs about the Workshop rules.
  • Added a quick link for the editor to the browse window.
  • Localized the tags in the editor.
  • Added new tags: CGI, Cyberpunk, Landscape, Medieval, MMD, Pixel art, Relaxing, Retro.

  • Changed the publish process to require at least one genre tag being set.
  • Changed the tag auto-complete box to show all suggestions when clicking.

  • Fixed web wallpaper mouse position being incorrect with varying DPI settings.
  • Fixed image deselection in wallpaper properties.
  • Potentially fixed the "startup error code 3" issue. Now Wallpaper Engine will continue loading in this case and not quit.
  • Attempted to fix a crash that occured if an external application closed the wallpaper windows (for videos).
  • Attempted to fix a crash in the editor that occured if it was used without Steam running.

Hello everyone,

A new patch for Wallpaper Engine has just been released that should address various small issues and it also introduces two new features: Desktop icon opacity and a Workshop cache, so you can continue to browse through all subscribed wallpapers even without Steam running.

The Icon opacity can be adjusted in the options for results such as these:

The Steam status is now indicated in the browser, to make it more obvious what's going on behind the scenes:

The browser still needs to be opened once while Steam is running to actually create the cache data, however.

A new experimental feature allows you to preload entire wallpaper videos into memory, to prevent your disk from being worn out due to streaming. Since the 64bit executable is still not fully used (and generally can occupy a lot more unnecessary memory) this feature may crash the application if you have multiple monitors and attempt to preload GBs of video data for wallpapers.

The Steam game language will now actually be used if you have chosen the "default" language setting and the video error notification includes a click callback that will bring users directly to the FAQ. This will hopefully make it easier for everyone to debug recurring problems like video tearing/black screens on hybrid GPU systems.

The next big feature that I intend to implement is support for random wallpapers/shuffling/playlists. This should be ready in Q1 2017, possibly end of January.

As usual, leave a comment, visit the bugs forum or let me know via e-mail ( ) if you're having problems or questions!


Full changelog:

  • Added experimental video in-memory playback, which will precache the entire video and does not stream from disk.
  • Added a Steam status notification to the browser, to make it easier to understand what is going on behind the scenes.
  • Implemented a Workshop cache, so Workshop wallpapers can be selected without Steam running.
  • Added click callback to video error message which will open the FAQ thread.
  • Added better tray advertisement on initial run.
  • Added icon opacity slider to the options.
  • Attempted to fix desktop staying see-through after Wallpaper Engine was closed (which caused issues when alt-tabbing from borderless fullscreen games).
  • Made web wallpaper process per-monitor DPI aware.
  • Changed default video volume to 50%.
  • Added warning modal if the app is run on an OS older than Win 7.
  • Added FAQ link to context menu.
  • Added tags "audio responsive" (automatically set) and "multi-monitor optimized" (manually set).
  • Improved GIF animation time-refresh sync.
  • Added screen resize fallback.
  • Set CEF to ignore WebGL blacklist.
  • Reworked editor help dialog to simply link to tutorials.
  • Added 'Remove Wallpaper' button for single monitor setups.
  • Made it possible to actually read the current game language from Steam (when the app is launched through Steam).
  • Added translations for Persian.
  • Added translations for Russian.
  • Added translations for Swedish.
  • Added translations for Simplified Chinese.
  • Added translations for Turkish.
  • Added translations for Italian.
  • Added translations for Dutch.
  • Added translations for Brazilian.

  • Attempted to fix auto start not working (and also restarting being blocked).
  • Fixed ' handling for wallpaper preview images.
  • Fixed filter menu animation stuttering on some systems.
  • Fixed certain windows being pushed offscreen with high DPI.

Hey all,

This patch adds proper support for animated GIFs and WebMs along with a system to localize the entire UI of Wallpaper Engine! If you want to help with localization, you can get the necessary instructions from here: any help with translations is welcome!

You can now load GIFs into Wallpaper Engine and also easily share them on Workshop. Previously, a hidden trick existed to open a GIF as a wallpaper, but it resulted in high CPU usage, so I didn't make it official. The new system is using a custom implementation (instead of leveraging CEF/Chromium) that basically converts GIFs into sprite sheets. CPU, RAM and GPU load will be minimal with this system and a lot better than the old implementation.

On top of that, you can tweak the speed of the GIF in the browser and the scheme (window) color is derived from a GIF automatically to make things easier!

When importing a GIF through the editor, getting it ready for Workshop, you can also control how the GIF is rendered and apply some noise reduction, which can come in handy for GIFs that suffer from notable dithering:

To get started on pushing GIFs, you can check out this new guide:

Some cool GIFs that you can check out locally:

WebMs can now be pushed to Workshop and also loaded directly from a file - along with speed and volume options just as other videos! However WebMs will be played through CEF/Chromium, which means they will take more resources and processing power than mp4s.

The translation system recognizes all of Steams languages and I have preemptively added all of them. You will need to choose the language in settings/general to switch it:

Right now there are already a lot of German and Polish translations and a few strings in Simplified Chinese (thanks to Lyvelion and 伊织). Like mentioned before, if you want to help translate anything, check out the instructions here:

Properties of wallpapers will no longer need to be reset now, if the creator has changed them, and all scenes also automatically received a tweakable playback rate property with this update!

New Features
  • Added native support for GIFs through sprite sheets in scenes.
  • Added native support for WebM.
  • Added scene playback rate property.
  • Added new template for GIFs with various import options.
  • Added support for GIF and WebM through 'Open from file'.
  • Implemented translation system for core application and UI.
  • Added German and Polish translations for all UI windows except editor and some Simplified Chinese strings in various locations.
  • Added combo box to switch the language of the UI.

  • Fixed wallpapers in browser being switched when arrow keys are pressed although another control is highlighted.
  • Fixed web wallpapers not saving cookies and JS local storage data.
  • Fixed web wallpapers not loading plugins (e.g. Flash).
  • Fixed web path imports with ' in the filename.
  • Fixed property import controls being hidden in 'small mode'.
  • Fixed app wallpapers crashing when using the 64bit executable.
  • Fixed URL encoding for file paths sent to web wallpapers.
  • Fixed web wallpapers turning white immediately on load due to Steam sending an unnormalized installation path.
  • Fixed mouse sluggishness in editor when importing an app wallpaper.
  • Changed how wallpaper properties are saved. Now only the values are saved, so updating the properties of a wallpaper does no longer require users to manually reset them.
  • Fixed overlapping wallpaper titles in browser.
  • Fixed a potential crash when an invalid wallpaper file was opened.

The next update will include localization support for the editor window and a "support & troubleshoot" dialog. This is meant to mitigate some of the recurring problems, like audio recording issues with the Razer headsets or Nvidia Optimus. Non-english speaking users are also dependent on a translated version of the solutions to these issues.

As usual, leave a comment, visit the bugs forum or let me know via e-mail ( ) if you're having problems or questions!

Hey all,

A new update for Wallpaper Engine has just been released, adding a bunch of new features, that improve the whole experience, and fixes for a few bugs. Read on to get a quick overview about what's new:

The browser allows you to filter your installed wallpapers more precisely now:

It also remembers all URLs and local files that you previously opened (of course you can also easily remove these again afterwards!):

A favorite button allows you to instantly fave wallpapers right from the browser and the file size of each file can be seen now as well:

Multi-monitor systems can now pause maximized or fullscreen wallpapers per monitor, which is the new default behavior. You can still go back to the old behavior in the options though:

Recent wallpapers can be instantly switched to from the tray menu instead of having to open the browser:

And web wallpapers can make use of a new property control for combo boxes:

Last but not least the crash handler has been improved to instantly scan for troublesome hooks in the application that are known to crash or corrupt Wallpaper Engine, which some users have suffered from. So if a potential culprit has been found, you might be able to fix the crash instantly instead of having to send me the .mdmp file and waiting for me to check it out, simply by excluding Wallpaper Engine from the hooking application. The web wallpaper process was also not handling crashes at all previously, which has been fixed now. So if your web wallpapers keep turning white, you should get a message and a crash dump now.

Complete changelog:

New Features
  • Added various filter options for wallpapers into browser.
  • Added per monitor pause option (maximized and fullscreen) to multi-monitor systems and made it the default.
  • Made wallpapers unpause while Aero Peek is active.
  • Added sort by update date and file size to browser.
  • Added file size to wallpaper details in browser.
  • Added list of recent wallpapers to tray context menu.
  • Persisted all local files and URLs to config.
  • Added favorite button to browser.
  • Added combo box control to wallpaper properties.
  • Added hook detection to crash handler to help the user fixing crashes more quickly.

  • Fixed audio processing not keeping up with higher framerates.
  • Fixed wallpaper config not saving wallpapers of inactive monitors.
  • Fixed requestAnimationFrame not keeping up with high framerates.
  • Fixed web wallpaper not generating mini dumps when it crashes.

Hey everyone,

An update for Wallpaper Engine has been released that will make it possible to select custom images or whole directories with images to be shown inside a web wallpaper! This means that you can build custom image slideshows now or simply create cool things with JavaScript ontop of everyone's favorite backgrounds.

Check out this new tutorial to learn how you can build a web wallpaper with support for customizable images:

A few other improvements have found their way in, including improved behavior for audio responsive wallpapers, the 50 FPS limit from the UI is gone and wallpapers you selected locally (for example video files) will now show up better in the browser with the ability to change their properties (like volume and scheme color)! Also, you can now more easily delete your projects from the editor open file menu.

The next patch will fix wallpapers pausing with maximized/fullscreen windows on multiple monitors and possibly some more usability improvements and fixes that have been requested (which I still need to do more reseach on).

  • Fixed properties with single quotes to be escaped improperly and causing the UI to not show any properties.
  • Fixed most FFT inconsistencies for different hardware settings and used a fixed range with up to about 22khz.
  • Fixed web wallpaper render process silently crashing if being closed with an audio wallpaper active.
  • Fixed local wallpaper files not showing & saving any properties.
  • Attempted to fix auto start with high priority (although I can't speed it up much if the hardware doesn't allow it, but now it may at least be more reliable when it takes longer).
  • Attempted to improve pausing with certain full-screen games.

  • Added file and directory selection to wallpaper browser.
  • Implemented custom file/directory import system in web wallpaper.
  • Added full-screen GIF hack (open from file, all document types) unfortunately it performs terribly (it's just using Chromium).
  • Made max FPS dependent on max refresh rate of the system.
  • Made it possible to delete wallpaper projects in the editor.
  • Added icons to volume/playback rate and audio recording controls.
  • Enabled audio of video wallpapers in the editor.
  • Added options for video looping which may help in some cases to improve the smoothness of loops.

Make sure to fully close Wallpaper Engine when updating. If you're having issues, try verifying the files over Steam first.

Hey all,

A patch for Wallpaper Engine has just been released that should pave the way for easier model importing. A lot of limitations have been lifted and the model and texture importers have been replaced with open source libraries to enable support for more formats. On top of that, the model importer now does a better job optimizing the model, adding missing texture coordinates or normals, and the texture importer will allow you to import images of any size now (between 16 and 8192 pixels in width and height. If necessary, they will be downsampled to the next power of two, as this is a hardware requirement). You can now also import models without textures and simply set a constant color in the editor afterwards.

Model formats that are supported now:
  • FBX (latest version not supported anymore, but they're working on it)
  • OBJ
  • DAE
  • 3DS
  • X
  • LXO

Texture formats that are supported now:
  • PNG
  • TGA
  • BMP
  • PSD
  • ICO
  • GIF (NO ANIMATION YET - but you can use them in web wallpapers as before)
  • DDS

Keep in mind that the UI and the shaders are pretty much still the same! Those will be revised separately in a later update.

Complete changelog:

  • Fixed Steam detecting Wallpaper Engine if the internet disconnected and reconnected and WPE was started *through* Steam before.
  • Fixed local app wallpapers not being able to be opened without tags.
  • Fixed projects with illegal characters for directories in their title to fail import.
  • Fixed NaNs und Infs in audio buffer after running FFT code.
  • Attempted to fix overlapping border when the UI windows are maximized.
  • Attempted to fix more Media Foundation video issues (looping, flashing, screen going black).
  • Fixed file imports with ' in the name.
  • Fixed audio processing for web wallpapers not enabling in a certain scenario.
  • Fixed audio callback context not being cleared when switching between web wallpapers.

  • Made it easier to get the konami achievement (*about* time).
  • Added uninstall command to build script that will at least close the main application so Steam can delete it (during verify too!).
  • Added 'order' key for wallpaper props in project.json.
  • Implemented AssImp and removed FBX SDK and tinyObj.
  • Made it possible to import models that don't have textures.
  • Made it possible to import models with more than 65k vertices.
  • Increased texture size limit to 8192^2.
  • Enabled model import for fbx, obj, 3ds, lxo, blend, x, dae.
  • Implemented FreeImage into the texture compiler.
  • Enabled image support for png, tga, jpeg, bmp, ico, gif, psd, dds.
  • Made it possible to import non-power-of-2 images, they will be downsampled with bilinear filtering to the next power of two.
  • Adjusted eagle flag projection so it fits better on wider screens.
  • Added color and alpha options to current generic shader.
  • Added unsubscribe button to browser.
  • Updated GLM.
  • Added more verbose log output to DirectX safe start (used during auto start, to prevent crashes).
  • Changed FFT spread to widen lower frequency area more (now using an exponential function instead of trig).
  • Added error logs and output to CreateProcess and Steam item subscription.

To properly apply this patch, make sure that you close Wallpaper Engine and let Steam update it!

Hey all,

A new patch for Wallpaper Engine has just been released that brings some new enhancements for web and video wallpapers and some fixes!

Web wallpapers can now use user options (properties) like custom colors, checkboxes and sliders. They can also access the general settings, like the FPS limit, and audio data, so you can build your own visualizers much more easily now. You can now also edit your web wallpapers more easily, when you are changing your files and save the wallpaper, it will automatically be reloaded. Check out these new guides to learn how to use these features:

Video wallpapers now got a rate and volume control in the wallpaper browser.

Since the previous patch, I introduced a custom verification check for app wallpapers (which was bugged on top of that, should be fixed now). But I still haven't figured out a good way to deal with verifying such files. Doing it manually is a very tedious and lengthy process, so in general you should export your apps to HTML if you can or convert them to videos to avoid this. Until I have a sandbox available for apps that I feel is secure enough, this verification system has to do. There are still some unverified apps on Workshop and I will try to get around to checking them out as soon as I can.

New features
  • Made user props, general props and audio data available to web wallpapers.
  • Added slider and checkbox controls to wallpaper browser.
  • Added live reload in editor to wallpaper types other than scenes.
  • Added audio processor to editor.
  • Added volume and rate controls to video wallpapers.

  • Fixed audio wallpapers not working after a video wallpaper was used (because the application was muted).
  • Fixed video wallpapers muting the entire application.
  • Fixed all app wallpapers being blocked although they were verified.
  • Made audio FFT a little less bass heavy.
  • Fixed editor stuttering when dragging the window.
  • Attempted to fix another UI start/shutdown crash.
  • Changed app launcher to require a successful hook of the wallpaper or otherwise cancel launching it.
  • Fixed a potential issue (race condition) in scene wallpapers.
  • Attempted to improve video looping behavior.
  • Attempted to improve wallpaper window management to avoid wallpapers getting in front of icons and similar issues.

As usual, if you are experiencing problems or have questions, you can leave a comment here or on the forums:

The next feature patch will be the first step to make model importing easier (scene wallpapers). My plan is to remove all kinds of limitations from the model and texture compiler as much as I can - the UI will not be revised just yet, that'll come later. So my planned next changes are:

  • Remove vertex limit of 65535 (it will not be infinite but around 4 Billion, which would be very impractical and slow mind you).
  • Automatically set texture coords if they are missing (they will just be set to 0,0 - tangent space for normal mapping cannot be generated then though).
  • Automatically generate normals if they are missing (generated from face normals and then auto smoothed).
  • Allow import of geometry with no materials (this will result in either a missing texture or a constant color for now, until the UI has been updated to deal with this).

  • Add support for JPEGs.
  • Increase max allowed texture size to 8192.

Restart Wallpaper Engine over Steam to properly apply this patch!

Hey all,

Another patch for Wallpaper Engine has just been released that fixes a few issues. It should provide more stability, video flickering/looping fixes for Win 7 and better support for unicode.

  • Fixed wallpaper browser crashing when double clicking a wallpaper.
  • Fixed application wallpapers not being adjusted correctly on additional monitors.
  • Fixed video wallpaper flickering on Win 7.
  • Fixed monitor previews not showing up.
  • Fixed unrecoverable boost filesystem errors to cause silent crashes or malfunction, they will now show a message box and then close the application.
  • Fixed unicode support in main application, editor, compiler and general UI.
  • Attempted to fix a dx11 crash.
  • Fixed web wallpaper clicking on multiple monitors.
  • Attempted to make desktop setup more stable and added check for high contrast mode.

  • Added separate launcher executable to prevent Steam from 'detecting' Wallpaper Engine. This is not enabled yet but will be enabled over the weekend.
  • Added a manual review system to application wallpapers and made it 'more difficult' to open unverified ones (see below).
  • Updated CEF to latest version.
  • Updated JSONCpp to latest version.
  • Added update inconsistency warning to UI (will be shown if Steam updates WPE while it is running).
  • Added a balloon tip that pops up when starting a video fails (e.g. 4k on Win 7).

As usual, if you are having any problems, write a comment here or in the forums or send me an e-mail to .

For all Razer Kraken users, apparently there is a way to get audio input to work: If anyone could try that I'd be interested to know if it helps.

Hey everyone,

An update for Wallpaper Engine has just been released that improves the wallpaper browser. You can now switch between wallpapers and monitors without having to re-open it, so your friends won't get spammed with the in-game notification anymore. The color customization has been moved into the browser, so you don't have to open the settings to adjust the wallpaper/Windows colors. And finally, there's some initial sorting and filtering now to make finding wallpapers easier.

I have also attempted to address stability issues with the UI, let me know in the comments if you are still experiencing crashes or post a thread in the bugs forum if something's wrong ( ). The custom colors you have set so far will be reset with this patch unfortunately, but it shouldn't take too long to set them up again with the new browser.

Coming next up are improvements to web wallpapers so they can read custom user colors and audio input from JavaScript plus a guide to illustrate the required setup for that.

UI improvements:
  • Added instant preview to browser.
  • Removed separate monitor window and integrated it into browser (only visible on multi monitor systems).
  • Made it possible to immediately adjust colors in browser.
  • Made it possible to open all three windows at the same time.
  • Added settings short cut button into browser.
  • Added text search and sorting to browser.
  • Added icon for favorite items in browser.
  • Added obvious tutorial to editor home screen.
  • Attempted to improve UI stability and responsiveness (CEF is now running in its own thread).

  • Attempted white window on Win 7 on multi monitor systems that don't use live wallpapers on all monitors.
  • Fixed WASAPI not restarting when default audio device changes (e.g. plugging earphones in).
  • Fixed WASAPI sometimes detecting 'silence' flag in error.
  • Attempted to fix frame skipping on looping videos.
  • Attempted to fix flashing on looping videos.
  • Fixed mouse coords in web wallpapers not being relative to their screen.
  • Fixed wallpaper monitor offset being based on monitor work area instead of full area (caused issues with task bars at the top).
  • Fixed web wallpapers being able to mess with the project.json (could potentially change it and link it to an executable).
  • Fixed UI crash on shutdown due to pending inter-process commands.
  • Fixed browser rating display.

  • Enabled error file logging by default.
  • Removed model material limit.
  • Added save button and save notification to wallpaper editor to make behavior clearer.
  • Changed order of menu items in tray.
