Running BTRFS and nouveau. The UI crashes, and put me back to the login screen after 30 seconds. This happens when I start softwares based on webkit (stremio, opera, chrome, etc). But generally only the first time. After login back and starting the program again, it works without crashing. The full dmesg error message is: [ 113.711453] [drm:intel_pipe_update_end [i915_bpo]] *ERROR* Atomic update failure on pipe C (start=5158 end=5159) time 130 us, min 1073, max 1079, scanline start 1071, end 1080 Repeated several times.
