At least in the nvidia driver, the recently released support for GLX_EXT_buffer_age means that we no longer have to preserve the contents of the backbuffer in an fbo in order to use glXSwapBuffers. As such, we can sidestep that and get a performance improvement.
I've linked the branch with the ongoing work for that, or you can test it in this ppa here : ppa:smspillaz/compiz-experimental
