Kenneth Russell explained to me the strategy that Chrome is using, and I think something similar could work for WebKit2. The basic idea is that the web process would create an HWND that is a child of the WKView HWND. The web process would render into the child HWND directly using D3D. The UI process would be in charge of sizing the child HWND so that it completely covers the WKView HWND. The child HWND would be transparent to mouse events so that WKView's event handling can proceed normally.
