Hmm.  On further consideration, I'm not sure this is right.  I think the intent was for the window surface of a ULW window to have a full surface even if it's partially off-screen.  So, perhaps macdrv_WindowPosChanging() needs to use the same calculation as macdrv_UpdateLayeredWindow() for that kind of window so the surface rect doesn't keep ping-ponging.

Also, the same issue exists in the X11 driver.

I'll have to discuss with Alexandre when he gets back.
