This happens because we leave accelerated compositing mode when a rendering update is scheduled in RenderingUpdateScheduler. The threaded compositor display refresh monitor is destroyed without completing the frame, so that the RenderingUpdateScheduler is left scheduled forever, ignoring any new schedule request. We need to ensure we complete the frame request before destrying the display refresh monitor to leave the RenderingUpdateScheduler in a consistent state.
