--- Comment #32 from Chris Wilson <chris at chris-wilson.co.uk> ---
What's happening in this bug digression is that we miss recomputing the
gc->pCompositeClip. Strange, very strange. Again, I have added some extra
debugging to narrow down why,

    sna: Include serial numbers in ValidateGC DBG

and would appreciate it if you could gather another debug log for me. Thanks.
