Comment 40 for bug 1860483

Could be. Bug 1860178's write-up seems similar to 1860483.

I have been able to use "Settings" in the sda1 install, and switched the
background to "black", at which point the raster type corruption in the
desktop went away. Now there's occasionally an odd speckled background
in the top tool bar, which blanks out to black around the top tool bar
icons and text, leaving something that looks like video noise between
the leftmost text/dropdown and the day/time text at the middle, and
between that middle item and the rightmost icon set. At the same time,
there's a little noise speckling on the left tool bar, and a bright
narrow vertical line between the tool bar and the desktop region; all
that blanks out to black too. The blanking-to-black occurs as the screen
cursor is traversed over the tool bars.

I am occasionally getting a non-response for item icons associated with
sda1 installs, just as I have been with items in sdb1. That kind of
looks to me like the system is losing or overwriting the pointer to the
app/item associated with the icon. For instance, I still can't get to
sdb1's "Settings"; I can click on any one of the "Settings" icons, the
activity indicator runs for a short period, stops, and nothing happens.
I've waited for a few minutes, up to around 5 or so, just to see if it's
a matter of timing, but nothing happens. And frequently, after that
happens, other items become non-responsive as well, up to the point
where the keyboard and mouse push-button handlers quit responding.
