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.
