I have been experiencing minor graphical issues on several Steam games. I have only encountered issues through Steam. GOG games launched through Heroic and Lutris seem to work flawlessly. I am using Arch Linux and my GPU is an AMD Radeon RX 6700 XT. I'd be grateful for any help
It might not be the answer, but I have had some games do very weird shit in the past (AMD GPU as well but on Windows). I found out that some games really don't like if you have applied AMD settings that override the game's graphical settings. Do you just have the AMD kernel driver, or have you installed the one with the Adrenalin from the AMD site? If you installed the Adrenalin software, you might want to try setting all the options for the game to only use game settings and not allow the AMD software to take over. If it is the one that ships with the kernel, then I am not sure how to change stuff that might be trying to override the game. Maybe see if there is a Proton version that might be better?
I am using the open source amdgpu driver. It's the one that's built into the kernel. I have tried multiple different versions of Proton both official and unofficial. I think this game is cursed to never work without trippy menus.
