Just a wild guess: Are you using X shared memory? Looking at the source
of windowBufferForWindow:depthInfo: it looks like I didn't check my  
patch
with shared memory (it doesn't work on OS X and one of the advices I  
found
when looking for a solution to get the art backend running with the X- 
org
server was to turn off shared memory; apparently I haven't turned it on
again though it didn't help).
