Okay, so I'm reassigning this to the kernel driver for now, though this might
just be a duplicate of another MSI related report here or in the kernel
bugzilla.

Option "MigrationHeuristic" has no effect with KMS. Disabling EXAPixmaps
probably just avoids the problem because it prevents hardware acceleration in
most cases. The corruption looks like bug 47266, would be nice if somebody
could find a working driver snapshot and bisect.
