Flickering or constant solid white screen with kernel >=6.1.4
After upgrading to kernel 6.1.4 or later I get either a strong flickering white screen or solid. Some details:
- Occurs after logging into Gnome, but not at the login screen
- Sometimes the full display is constant solid white and sometimes it flickers solid white several times a second
- When solid white, cursor is still visible and moveable
- No sign of processes crashing or kernel backtrace in logs
- Occurs with both Wayland and X11 sessions
After going through the patchset in 6.1.4 and testing while reverting, I was able to locate the commit that introduced the issue: drm/amdgpu: make display pinning more flexible (v2) . Reverting the commit eliminates the issue all the way through to 6.1.6 .
