[Bug 872832] [NEW] Unity-menu, top-panel and "frames" of windows disappeared and never came back.

 

Public bug reported:

It seems like the window manager (or the window system, I'll admit I
haven't quite understood the distinction yet) crashed, but I don't
really know what happened. The windows were still showing, but the
Unity-menu, the top-panel, and all the "frames" of the windows
disappeared. Alt+F4 didn't work to close programs, but I managed to
close Chromium and Eclipse using File->Exit. This has actually happened
before, but then everything came back after a few seconds - so I don't
know if it's related. I switched to terminal with Ctrl+Alt+1 and
reported this bug with apport-bug. I hope there's any useful debugging
information in the logs I submitted.
