Please test the patch Chris already replied with to your first mail. It
might fix your issue here (if it's just a fence being stolen a bit too
early). If that does not help, I'll have to stare at the picture some more
to decode the type of tiling/swizzling going on. Maybe different pictures
of corruptions might help for that.
