I have looked into it. This appears to be a Firefox bug when HDR is enabled on wayland and the website is using webgl. Firefox looks to be leaking wl_buffer objects which are causing a VRAM leak in the wayland compositor which then causes performance issues in the AMDGPU TTM buffer object management.
Nice dig. Could you share more about how you narrowed it down in the end? Is it a known issue and you just had to confirm it applies, or did you identify all of this yourself?
I agree. I wanted to make a note for anyone else seeing odd behavior, but I'm working on figuring out what sort of degenerate behavior this hits.
