Yes, this is a delicate setup. You should really use the same Qt version, otherwise
bad things will happen (TM).

QWebEngineView uses the SceneGraph in the QtQuick module as a compositor.
So yes, even if you use Qt5WebEngineWidgets it uses Qt Quick, which in
turn relies on a graphics part directly supporting OpenGL, ANGLE, llvmpipe, 
or the Qt Quick 2D Renderer.
