Sometimes after resuming from hibernation, client windows are corrupted like
shown in screenshot (contents of firefox tab, compiz-0.8 as window manager).
Restarting compiz doesn't help, but restarting the clients (in this case
firefox) does get rid of the corruptions.

This might be related to bug #80727, but it does not always lead to a GPU hang,
so I've opened a separate bug for this.
