When all of the fences have been used, the compositor needs to reset +one so that it can be reused. It does this by first waiting on the CPU for the +fence to become triggered, and then sending a request to the X server to reset +the fence. + +If the compositor's GPU channel is busy processing other work (e.g. the desktop +switcher animation), then the X server may process the reset request before the +GPU has consumed the fence. This causes the GPU channel to hang. + +Fix the problem by having the compositor's GPU channel trigger its own fence +after waiting for the X server's fence.
