Bug 1493 - GL ES does not work since Jan 9 in PowerVR SGX 535, Intel The mapped flag needs to be set on the stage otherwise clutter_actor_queue_redraw will never queue a redraw and never draw anything. In these two backends there is not really a way to hide the stage so they both set the mapped flag immediatly when clutter_actor_show is called.
