<pre>This can be easily tested with MiniBrowser, for example:
$ WEBKIT_FORCE_COMPOSITING_MODE=1 MiniBrowser --bg-color="rgba(255, 0, 0, 0.70)" -e
The background is opaque white, and there are artifacts when resizing the window (because the web process is not rendering backgrounds when setting a web view bg color). This needs changes in the UI process when using the redirected window, but also in the web process. And of course it always happens with the threaded compositor when ACC mode is always enabled.</pre>
