Corrupted window area in a Gtk+2 app (Pidgin), after a floating "hover
notification" box has disappeared, the area under it is corrupted.

Corrupted pixmaps (cached, I suppose) all around in Gtk+2 at least, and
increasingly in Firefox (latest beta 22.0). Gtk+ corruptions seemed to appear
after upgrading to latest GIT version of the Intel driver. Kernel upgrade from
3.8.13 -> 3.9.3 made no apparent difference.

Occasional corruptions in Firefox have been around for quite a while (and
reported separately), so that's probably another bug entirely.
