It's not actually the time that determines if the eye mask is in the  
right place, it's the initial placement of the window... it's as if  
its placing the mask at a location in the window using root-relative  
coordinates when it should be using window-relative coordinates...

I am stumped... gonna look at all the x-protocall calls in quartz-wm/x- 
window.m and do some debug spew on them and compare to the same spew  
in the old working version... hopefully that'll reveal the problem...

I tried looking in xeyes to see how it treats the two layers  
differently, and it looks like it treats them exactly the same... =/

Yeah, it's not happening on resize though...
