Here is what I see : when zooming out I have no problem, I haven't seen any 
problem when drawing, but when zooming in, only the top left quarter of the 
image is displayed, but when painting on the new area it works for a while 
and then crash.

Is that what you have also ? Or is there an other problem ?
I tried on XRender accelerated hardware and it was very slow, but maybe all 
the piece aren't yet together or the debug information are the cause.
