I just wanted to make sure that someone is aware of this problem.  Fences have a tendency to hop around among my displays when using multiple monitors.  It most often happens when I turn off my main display which is connected via DisplayPort.  Since it drops out entirely, the fences go to one of my DVI displays instead.  They don't always go back when the main screen goes back on.

Is there a way to either fix this or manually trigger an entire screen full of fences to go to a different display?
