Chromium does workaround of scrolling with touch when child window is used for DirectComposition. It looks better to import it to gecko for WebRender.
https://bugs.chromium.org/p/chromium/issues/detail?id=871257

There were 2 bugs that might be affected. Bug 1487564 and Bug 1455518

When I just added WS_EX_LAYERED | WS_EX_TRANSPARENT | WS_EX_NOREDIRECTIONBITMAP, compositor widow creation was just failed :(

When it happened, I set security.sandbox.gpu.level=1 pref by mistake.
