This is tricky, but the behavior of compositing has been discussed


If this doesn't clear it up, tell me and I'll try to provide a better
explanation (with pictures and stuff).

I'm not really familiar with how -xlib handles this (it seems to have
very limited handling of transforms), but -gui is correct afaict (I have
no problems, regardless of GraphicCompositing, with back-art).
