Bug Description
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-
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-
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.
/var/crash now has contents
ubuntu@ubuntu:~$ ls -la /var/crash

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/
The issue is likely graphics driver related.. though I've tagged kernel.

this is quite probably a duplicate; experienced before I suspect
