Not sure if I am doing is properly, but I performed a git bisect between 5.9 and 5.10 on drivers/gpu/drm/amd. Note that none of the supposedly "good" commits actually fixed the issue. I just mark them as "good" because those commits either cannot modeset to my monitor's resolution, or the kernel fails to write certain registers to my GPU and causes my display lose signal and go to standby. So technically the "first bad commit" is just the first commit that I can boot into SDDM/KDE and can also reproduce the issue. Please let me know if there are anything else I can help with. I have a spare Vega 64 (Vega 10) card lying around, but it has its own memory clock issues as far as I remember =/ -- You may reply to this email to add a comment.
