Public bug reported:
Ubuntu groovy QA-test (live)
I changed screen setup to match my setup (2x 1920x1080 displays one
above the other, the default-right got moved to above my other monitor).
On doing this screen background disappeared and became black.
On using system, background changes from all BLACK to blocky-low-signal
digital-tv like blocks that is unusable for reading detail on screen,
but it seems to return to all black in time (or with use)
I can change wallpapers and that appears to work correctly at least for
a time, the new wallpaper will disappear (again with time or use) and
wallpaper goes dead-black again (though primary screen may also have
mimimized windows appearing in blocky-low-signal-tv like; not neat and
readable but messy & changing.. nice easy black on second monitor)
I've been unable to take screen dumps, not sure why.
/var/crash/ is empty
Minimized windows do not disappear from screen, hitting minimize on a
window does nothing (visually). It's these images that appear to become
the blocky-blotchety-low-signal background that eventually becomes all
black. Once a window was made to minimize, even though image is fully on
screen, clicking mouse on visible-window works now like you're clicking
background (though minimized window is displayed). If i could get
screendumps this effect could be lost.
Currently this report is low quality (can't get screencaptures, no
photo), but the behavior differs between my screens. My upper screen is
a lot less problematic than my-lower (primary) display.
Opening the menu blackens (completely) the background on lower display
(yeah, the older windows that were minimized can be distracting..) and
improves usability.

I haven't worked out a pattern on what causes the strange behavior, it's
not all the time -- however I can create the worst of it by just
changing the screen orientation (even just a little). Do that and any
chosen wallpaper is gone, and my background appears to be filled with
detail from possibly prior? pages!?? eg. rather than my two screens
directly one above the other, I move to top to be slight left/right a
little..
As I type this into firefox window (on lp), I'm getting glitches on the
background that is somewhat distracting/annoying. I wouldn't use this
system as it is.
The issue is likely graphics driver related.. though I've tagged kernel.
