I don't think this is a Unity bug. I think this is a problem with the Intel xorg driver. Using normal gnome/metacity on a GMA 950 based computer, running glxgears gives dodgy results. Start intel_gpu_top in an xterm, re-run glxgears, and you get 60 fps solid.

Unity/Compiz/etc/etc will probably suffer from this same problem. Its a Heisenberg Performance Problem. It doesn't occur when the GPU is being watched.
