I suspect an expose -> paint -> expose -> paint -> ... loop.  I'm
working on a patch that will eliminate all such loops.  I'll make sure

But I'm aware that there are lots of focus problems -- it's another area
that I need to take a close look at in the near future.

This deserves another bug report; can you provide a test case too?
