      When using the Scene3D QML component in a QQuickWidget, QAspectThread will get in a busy loop while the containing widget is not visible. This does not seem to be related to OnDemand rendering.

      The attached example shows the problem. QAspectThread consumes CPU in a loop until the checkbox is clicked, making QQuickWidget visible.
