Fix screen issues on Linux/Steam Deck
By Noctus
I will hopefully come back and make this guide more organised and detailed.

For now, It will just be a summary of what to do.

Fix the issue(s)
Apologies if this is too technical and not detailed. I do not have much time to spend on this right now, and when/if I do I will be sure to come back and fix up this guide to ensure non-technical users can easily understand it as well. Hopefully following these instructions does not prove too difficult, if I've done it right. Good luck.

1. First, right click the game > properties > compatibility > force compatibility > Steam Linux Runtime
We do this to ensure the game runs directly on Linux without any compatibility tools since the game runs natively on Linux.

2. Open up a terminal, install (if not installed) and open 'nvidia-settings'.
(Hint: open it by typing 'nvidia-settings' in your terminal after installing it)

3. On the tab selection menu, select 'X Server Display Configuration'

4. Click Advanced

5. Check "Force Full Composition Pipeline"
NOTE: This will screw with some other games, but if you don't click 'Save to X Configuration File' it will reset on computer restart anyway so it should be mostly fine. Otherwise, make sure you change it back before playing other games.

6. Click Apply and exit the settings

7. Restart/Launch the game

Note: You have to do this on every reboot of your system. To have the setting set itself, you need to run nvidia-settings as root (using sudo, for example) and after following the above steps and clicking 'Apply', you need to click 'Save to X Configuration File'. I do not recommend doing this unless you know what you're doing, or at least making sure to set a reminder/note to change it back once you're done with the game.

Note 2: This only works for those using X Server as their display manager. If you don't know what that is, your system probably uses it anyways. If you were able to follow the above steps your system almost definitely runs X Server.
