Are the artifacts captured in a screenshot, or only in a photograph taken from the screen? It might be helpful if you could attach a picture showing the artifacts either way.
both on screenshoot (using ksnapshot) and photograph
screenshoot: (~10MB) http://neutrinus.com/tmp/kaczka.png
(this is worst case - normally its not like whole windows garbaged)
Can you bisect?
yes :) (but it may take some time)
