Symptom of flickering during resizing seemed to be affected by window rendering configuration

- [1] HWND + Compositor window + DXGI_SWAP_EFFECT_FLIP_SEQUENTIAL SwapChain
  + D3D compositor with double buffering
- [2] HWND + Compositor window + DirectComposition + DXGI_SWAP_EFFECT_FLIP_SEQUENTIAL SwapChain
  + WebRender without WR native compositor
- [3] HWND + Compositor window + DirectComposition + IDCompositionVirtualSurface
  + WebRender with WR native compositor

With [1], I saw significant flickering. But with [3], the flickering was less amount.

By the way chrome browser normally use "HWND + Compositor window + DirectComposition + IDCompositionSurface".

With [1], I saw significant flickering. But with [3], the flickering was less amount. When [3] is used, the flickering seemed less significant than chrome browser for me.
