Comment 1 George Lukas 2024-06-24 20:20:39 UTC 
This seems to happen only under Wayland session. X11 seems fine

Do these warnings get printed every time this happens?

Yes, it does. I'm not sure if this is related to freedesktop, but there I also reported this issue.

Comment 4 Zamundaaa 2024-06-25 17:56:41 UTC 
This is definitely a kernel issue then. drm/amd is the right place to report it
