Every couple of hours in Forza Horizon 5 I get this kind of visual artifacting. When it happens, FPS tanks heavily first. Sometimes it recovers on its own (like in the video), other times the game crashes with this log:

OCCT and FurMark both run fine for hours without errors, and other games don’t show this issue at all. It really seems isolated to Forza.

I’m running an RX 7600 with Proton Experimental (bleeding-edge), kernel 7.0.3-arch1-2, and Mesa 26.0.6-1.

Any help would be appreciated.
