some players encountered a problem when running Get The Gems in Exclusive Fullscreen mode. The problem only occurred in certain combinations, depending on the operating system, the GFX card and the DX version.
There are now 3 options when you launch the game via your STEAM library:
1: Play Get The Gems 2: Play Get The Gems (Window Mode - Fixed) 3: Play Get The Gems (Window Mode - Resizable)
Please use mode 3 if the Exclusive Fullscreen Mode doesn't work for you.
