It should work. What version of Qt are you using?  There was a regression in 
Qt 5.1 that could trigger if you build against EGL instead of OpenGL. This 
would cause CPU copying on every frame. In Qt 5.2 though, QGraphicsWebView 
should always render directly to the QGLWidget, if using accelerated 
compositing is enable and a Qt GL context was found.
