Tested with Proton 8.0-2 and Proton Experimental.

Please describe your issue in as much detail as possible:

(Not sure if the issue is Proton, Steam, my GPU driver or a combination.)

When disabling the Steam overlay most proton games have graphical artifacts in the bottom of the screen if a non-native resolution is used. It's small flickering black boxes. I have a 3840x1600 monitor so all other resolutions than that results in the glitches. Unfortunately I can't run most games at that res. When the overlay is enabled all resolutions work fine.

Steps for reproducing this issue:

Find a Steam Play game
Right-click game and disable Steam overlay while in-game
Start game
Change to non-native resolution, e.g. 1920x1200
Make sure game is fullscreen

Hello @mlandalv, in general, we're tracking issues with games run with Proton in the Proton issue tracker, so I've transferred this issue report, but this reads like a video driver issue, not an issue caused by the absence of the Steam overlay. This issue should be mentioned to your video driver vendor.

Setting that aside, please copy the contents of Steam Runtime Diagnostics from Steam (Steam -> Help -> Steam Runtime Diagnostics) and put it in a gist, then include a link to the gist in this issue report.

Thanks @kisak-valve. I updated the initial post with Steam Runtime Diagnostics. I'm using RADV but will test with AMDVLK later today/tomorrow and file a bug to the video driver vendor instead.

I tried and everything is fine with AMDVLK so this is an issue with RADV.

Thanks for your help. Feel free to close.
