Public bug reported: I'm unsure as to where the fault occurs- I was unable to fully upgrade with 'update-manager -d' as it failed on some packages, and I resumed with aptitude full-upgrade, which left several packages (compiz, ubuntu-desktop, and others) unresolved, though apparently they're resolved now. When I flip between windows (unusually of chromium, or opera), or especially between different desktops (or sometimes access dash) my laptop will freeze, with all windows and taskbar/titlebars disappearing, showing only the wallpaper and the cursor. The programs continue running, and there are no problems with network or sound (a video chat worked fine through such a lockup). After a few seconds, everything will return to normal. Earlier in the day (though not in the timeframe of this report), I did see kernal errors due to drm:drm_get_fb having an invalid buffer address in /var/log/syslog. ubuntu-music-dea is also causing errors (unity-music-dae[2223] trap int3 ip:7f88248a4473 sp:7fffc8b5f8f0 error:0), which are recorded in syslog. This may impact the issue, though I doubt it. Thanks!
