(Whiteboard: [gfx-noted][games:p3][platform-rel-Games]) 

With Silk, we spend 1 vsync interval rendering/painting and another vysnc interval to composite, introducing one frame of latency for smoothness. Ideally, in some scenarios such as gaming / VR, we could try to do both rendering/compositing in 1 vsync interval to remove this added frame of latency.

I have removed the [webvr] tag, as WebVR no longer depends on this with the dedicated VR rendering path that landed in Bug 1250244.
