Public bug reported:
I am not 100% sure I am reporting against the correct package. I have
been using Ubuntu Studio 19.10 development release today, and I am
seeing colour blotches over the screen (at the place of focus) when it
is updating near the mouse pointer, or text being entered into the
terminal. When using the browser, the whole page is blotched out after
the page loads. Moving the mouse to the stop of the screen (or away from
the problem window) normally allows the page/text to display without
blotches.
Twice, I have ended up with a green screen of death, which I recovered
from by turning the machine off.
I have tried the latest kernel (linux-image-5.0.0-17-lowlatency :
5.0.0-17.18), and the earliest Eoan one I have (5.3.0-13-lowlatency).
I have Ubuntu Studio 18.04, 1810, 19.04 on the same machine, and I can
use these for an extended time without seeing the same problem.
If I was able to set the importance, I would go for "high".
If possible I will attach a video (if launchpad will let me). I tried a
screen shot, but moving the mouse away to click on the screenshot app
makes the blotches disappear.
