Details

On Windows, WebRender with native compositor uses many DirectComposition Surfaces, it seems to add GPU tasks at DWM. one framebuffer with one Surface seemes to reduce GPU tasks at DWM. Chromium uses its combination.

This might help the followings.

  • Native compositor support when hardware stretching is not supported of Bug 1620491.
  • Add overlay support with software WebRender of bug 1873796.
  • Overlay support of Bug 1901334 .
