Font corruption example.

After resuming from suspend or hibernate, some characters in some font
instances do not display correctly. They seem to have some pixels missing.

This bug seems to have been greatly mitigated by the update I made today with
intel-linux-graphics-installer (excerpt from yum.log):

Jun 05 20:19:35 Installed: libva-utils-1.1.1-2.fc18.i686
Jun 05 20:19:38 Installed: mesa-libOSMesa-9.2-0.7.20130528.fc18.i686
Jun 05 20:19:39 Installed: mesa-libGLES-9.2-0.7.20130528.fc18.i686

but the corrupted characters are still there in some cases (see "S" from
"COMPOSE" in the attached picture).
