My guess is that the changes have just resulted in nothing actually  
being drawn.  What you're seeing in the background there is actually  
just the uninitialized garbage that happened to be at the memory  
location allocated for that backing store which was previously used to  
draw a quartz-wm widget.

Can you provide me with your simplified test case.  That'll be easier  
than dragging the xterm window resize around every time I want to  
debug this.

Thanks,
Jeremy
