My guess is that it is a double application of the drawable offset when
doing a CopyRegion swapbuffers. Does the corruption move in relation to
the window as it moves?

This suggests that [my] recent changes to the ddx are to blame, and
certainly a bisection on -intel might help - though it's probably just as
easy to test before the shadow+dri changes to confirm.
