Public bug reported:
Attached is an example of a problem behaviour of horizontal black lines
which affects Evince, Guadayeque and other programs on my desktop.
The corruption is progressive (when first opened, apps don't tend to
have the problem, happens on a per-window basis, (moving another window
over the area is not corrupted) and seems to permanently affect certain
in-memory glyphs (e.g. even after a restore and maximise, the icons in
some applications remain similarly corrupted).
