I'm seeing similar stuff with nouveau; it seems mostly to be some kind
of buffering issue, window content is not being updated when it should,
and I wind up with old content still there, or apparently blank areas.
Ben was of the opinion it may well be in the Shell stack somewhere
(probably clutter, if I had to guess). I'm meant to test with LXDE or
KDE or something to see if that 'fixes' it, but haven't got around to it
I haven't seen the out-and-out corruption in your first screenshot,
though, so I think that's something different.
