Hi everyone,
I’m having an issue with fullscreen games on Zorin OS.
When I run a game from Steam in fullscreen mode (not windowed), everything works fine. However, if I switch to another application (e.g., Alt+Tab) and then return to the game, the display breaks:
- The screen becomes mostly black
- The game appears as a very small window in the top-left corner
- I can’t restore it to normal fullscreen
The only workaround is to force close the game and also the Ubisoft launcher (I believe it’s Ubisoft Connect).
Game: Heroes of Might and Magic VI (probably others as well)
What I’ve tried:
- Running in windowed mode (works, but I prefer fullscreen - it has an ugly blue Windows bar on top)
- Tried to run with borderless window but launch settings in Steam are not working
- Restarting the game
System info:
- Zorin OS version: 18 Core
- Desktop environment: (GNOME/Xfce, if known)
- GPU: NVIDIA 4060Ti
- Drivers: proprietary (as advised by Zorin)
- Proton version in Steam: Proton Experimental
Has anyone encountered this issue or knows a fix? Could it be related to Proton, display scaling, or fullscreen handling?
Thanks!
