For now, one triple buffered swap chain is used with DirectComposition. But if multiple overlays are used, it might be better to use IDCompositionSurface instead of SwapChain. Chromium uses IDCompositionSurface when DC layers usage is enabled. https://cs.chromium.org/chromium/src/ui/gl/direct_composition_child_surface_win.cc?l=269

For example, display timing might not be synchronized between SwapChains.

For now, one triple buffered swap chain is used with DirectComposition. But if multiple overlays are used, it might be better to use IDCompositionSurface instead of SwapChain. For example, display timing might not be synchronized between SwapChains. We might be more performance. It seems that we could reduce memory usage.
