See attached screenshot. Visiting certain pages in firefox seems to be a good
trigger for this bug. First a rectangular splat appears in the firefox window,
which moves about when the window is scrolled. Moving into other windows causes
the corruption to change shape/position too. Sometimes, other windows also take
on the same corruption. Moving them leaves pretty trails over the desktop.
