Public bug reported:

The 2 compositing paths we were previously using have been removed from
Chromium. As an interim, we are now using 2 other compositing paths
(software compositing mode or mailbox compositing mode). However, both
of these will eventually be removed in favour of the delegated renderer.

Longer term, we want to hook the delegated renderer path in to the QML
scenegraph compositor so that we have a single compositor. However, as
an interim solution we could run a single-threaded browser-side
compositor for each webview (IIUC, this is how ContentViewCore and
ContentViewRenderView on Chromium Android work), and composite the
output of this in QML. This depends on fixing bug 1312081 first though
