Bug Description
To reproduce:
1. Start glxgears or similar.
2. Attempt to drag a window.
At best, the window will lag behind the mouse pointer by 2-3 seconds. At worst it can freeze the display totally until you stop dragging the window.
The odd thing about this is that glxgears claims to be running at 60FPS the whole time, even when the screen does not update for several seconds.
Also, the size of the glxgears window does not matter. Even a tiny GL window locks compiz completely.
This is almost certainly a problem related to nvidia binary driver. I'm using 310.

This is probably a regression of #764330. Opening a new bug as requested on that bug report.

I ssh'd into the machine to check top, and this is what I see while reproducing. Note I have a quad core, so 50% CPU = two cores maxed.
