Bug Description
Unfortunately I have no reliable way of reproducing this issue, but it seems that after some time of using Ubuntu (especially when browsing websites with firefox) the graphics are getting corrupted.
It starts with some small artifacts (single lines and pixels) and all of the sudden the entire screen is full of artifacts and the OS is basically unusable at this state.
Coincidentally, I've had this problem with Arch Linux before. I was able to fix it, by setting the power profile of the GPU to "mid" or "high" as described here: https:/
So to me it seems like this might be related to power management.
Doing some more testing with Ubuntu, I was able to fix the corruption when switching the profile to mid and then logging out and in again. Leaving the profile at default did not fix the issue after re-login.

I did some more testing today.
It seems one simple way to reproduce this is to just move the mouse pointer around on the login screen. At one point this even lead to a kernel panic (see attachement).
Again, setting the power profile to something other than "default" seems to get rid of the problem.
