Compositing breaks direct rendering, try running glxgears and rotating
the cube using open source drivers (nvidia do this properly). It can
also break Xv applications that use hardware overlays, usually using a
textured video backend is the workaround.

Kristians work is mainly at the prototype stage, we have a lot of work
to upstream, from the kernel graphics memory manager code to all of
Kristian and my changes to the intel driver, and also changes to the X
server etc.
