Obviously, it doesn't sync to the framerate with PRIME. On the other hand, nothing is displayed in the glxgears window. I have llvm 3.4-4 and Mesa 10.1-rc1 from Fedora 21 rawhide.
Make sure you are running a compositor.
Turning on compositing in MATE fixed it. Thank you very much. It seems I will have to keep Rawhide on this notebook. :-)
