Bug Description
After upgrading to 5.8.0-49, on a laprtop with intel graphics, graphics was suddenly extremely glitchy.
Icons from the desktop flash through the browser, windows top bar gets distorted, all sort of glitches appear, parts of characters are missing in terminal, scrolling is inconsistent and the whole desktop becomes unusable.
Under wayland the graphics are a bit more stable, but lots of glitches appear anyway, video reproduction in browser is stuttering and wobbly.
Booting with previous kernel 5.8.0-48 seems to fix the issues.
5.8.0-50 is broken as well.
this is the result of 'sudo lshw -c video' on my hp Elitebook 8470:
