Public bug reported:
I'm not sure if this is an xorg issue or possibly a Chromium issue, but
I'm playing it safe with xorg for now.
In the last couple weeks -- and I'm not sure after which update -- a
massive white horizontal bar has been appearing across my screen at
random moments, and it doesn't go away. The desktop still functions and
I can use the mouse, but this massive white bar covers most everything
and I can't see what's happening.
This seems to be a software issue, not a hardware issue. The only thing
I can be sure of is that it happens when trying to complete some kind of
function, and I think it happens when logging in to web sites, and
possibly when using Chromium. I know it happened when I had a student
logging in to his university Collab page in Chromium, and it happened to
me today when logging in to LastPass in Chromium. However, it's happened
to me at least 5 or 6 times in the past two weeks.
The obvious thing would be to try a different Chromium, but I'm curious
if this has happened to anyone else, and it still seems to be an xorg
issue, even if triggered when using Chromium.
I've attached a screenshot.
