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.
