Those windows are normally redirected as all other windows. However, you
can turn on an option in compiz that will detect fullscreen opaque
windows and automatically un-redirect them so that you don't lose
performance and can get accelerated XVideo without FBO or pbuffer

OpenGL games uses indirect rendering on xgl as direct rendering is not
supported yet.
