(Get the code!)
That looks to me awfully like an entirely idle gpu.
My hypothesis is that the driver has missed the vblank interrupt, so the MSC compiz is waiting on will never be raised.
Could you please add ‘drm.debug=0x1’ to your kernel command line and attach dmesg next time this happens? That should spit out appropriate messages to debug this.
