For about two months I encounter graphical glitches and/or flickering of the screen. By "glitches" I mean something like a horizontal white line (like you see with some VGA artefacts) which usually occurs when I interact with the panel in some way, say hovering or clicking. By "flickering" I mean the entire screen going dark for a split second.
This happens when other programs are open or with every (GUI) application closed. Sometimes the issue takes a while before it shows up, sometimes it manifests right after boot. But for the last couple weeks it's been happening basically every time I work on this machine.
I thought this might be a hardware issue, so I've tested other distros (Ubuntu, Mint, Fedora) in a live environment and I don't see get this issue there - though I haven't spent too much time with that.
I know this is pretty vague, but I don't know how to describe it better or pinpoint the issue further. If I can provide more useful information, please tell me how. For now, here's some basic information about my system, all updates applied as of 2020-10-05.
