If GL advertises this extension we'll use it to synchronize X with GL rendering instead of relying on the XSync() behavior with open source drivers. Some driver bugs were uncovered while working on this so if we have had to reboot the ring a few times, something is probably wrong and we're likely to just make things worse by continuing to try. Let's err on the side of caution, disable ourselves and fallback to the XSync() path in the compositor. https://bugzilla.gnome.org/show_bug.cgi?id=728464
