Just FYI, I've been seeing some of this in rawhide on my Radeon for a
while.  Claws does seem to be especially prone to the partial update
thing, but emacs shows it too.  I've not had the time to even begin to
track it down.

I see the partial updates with the 3.0 kernel.  When I run


instead, what I see, in addition, is horrific performance.  GNOME shell
achieves a new level of pain there, but even fallback mode hurts.  I've
not had any time to try to figure out what's going on there either.
