Compiz running at 100% cpu after resume

[Reinhard Tartler]

After resume, I noticed that my mouse cursor appears, but not the password dialog for unlocking my screen. On the console, I noticed that compiz runs at 100% cpu. I therefore used apport-cli to obtain a backtrace to learn where it hangs.

Except that apport cli obviously did not attach a stack trace :-/
