Title:
Since 5.8.0-49 Screen flickers and becomes unusable
Status in xorg package in Ubuntu:
Confirmed
Bug description:
On ubuntu 20.10, x-org. On upgrade kernel to 5.8.0-49, and then -50,
after the desktop has been on for a while the screen starts to
flicker. Blocks of text go missing. Letters in a string disappear.
Windows start flickering. The panel starts flickering and icons
disappear and reappear. The keyboard and mouse seem intermittently
responsive. After a restart it is OK for a little then starts again.
ubuntu wayland is no better.
Reverting to 5.8.0-48 fixes the problem completely.
I originally commented on #1923632 but that has gone private, and I
was asked to raise my own report. This one.
