Created attachment 343907 [details] testcase There's a certain situation using rAF to animate an alement where the sequence of frames rendered is not the right, which causes the animation to be flickery. I'm attaching a testcase where the problem can be reproduced. The problem is that instead of rendering the frames in the appropriate order 1-2-3-4-5-6 we're rendering 1-1-2-4-4-5-7-7 and this happens because we're triggering schedules in the ThreadedCompositor that should wait for a pending layerFlush and it's not.
