Title: Since 5.8.0-49 Screen flickers and becomes unusable Status in xorg package in Ubuntu: New 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.
