Hello @RoboMage, this reads like a video driver issue and should also be reported to the video driver vendor.
Alright, I opened an issue with AMD as well. (Hopefully in the right spot)
https://gitlab.freedesktop.org/drm/amd/-/issues/1810
Issue is caused specifically by the --usecase=workstation flag when installing the graphics driver. Omitting it resolves issue. Details here: https://gitlab.freedesktop.org/drm/amd/-/issues/1810#note_1169750
Nothing extracted yet.
Your system information
Please describe your issue in as much detail as possible:
Using the AMD proprietary graphics drivers for Linux causes Steam to render incorrectly. Games running in proton also suffer the same issue.
The prop drivers are required for some applications to run correctly (i.e. SideFX Houdini, Substance Designer, etc), and everything else on the system is behaving correctly. In the context of my current system, this rendering issue is unique to Steam.
