Could you test the > kernel later and report back? I am currently on your build it runs perfectly with both wayland/x11 I even did run glmark2 . When I wanted to make sure openGL is working etc, I have installed/run flatpak io.github.arunsivaramanneo.GPUViewer which just calls gl information from system and shows in a formatted view. GPU freezes that time with a lot of messages regarding nouveau. I am not sure if there is a co-incidence or related to this issue.
