Comment 45 for bug 815996

I experienced this bug on 11.10 and switch to 12.04 last week, on the 11st of May.
-> The desktop continued freezing randomly when I switch workspace as described in bug #880768.

Right now, the bug has desappeared but I am not sure I have done anything for that.

What I can see, is that the design of the popups (when you use Alt-tab or Ctrl-Alt-arrow) has regressed. They are not "pretty" any more (with transparent backgrounds) as they were when the desktop froze before.

If I go to the historic changes of the packages, I can see that "zenity" has been upgraded on May, the 12th. I also installed the x-server-xorg-video-install-intel-dgb and inteltool packages, but I did not do anything with them really, so I am not sure it has anything to do with the new status.

Do not hesitate to ask for more information (providing the command line to do if any, I am far from being an expert)
Cheers
