    // Note!
    // The Qt::AA_ShareOpenGLContexts setting is needed when we have multiple viz widgets in flight
    // and we have a setup where these widgets belong to different top-level windows, or end up
    // belonging to different top-level windows through re-parenting.
    // This is indeed the situation we encounter in this test application.
    // For example:
    // * Two viz widgets inside the same central widget => OK
    // * Two viz widgets docked inside two different dock widgets => OK
    // * One viz widget in docked dock widget and one viz widget in central widget => OK
    // * Two viz widgets as different top level windows => FAIL
    // * One viz widget in docked dock widget and one viz widget in floating dock widget => FAIL
    // * One viz widget in central widget and one widget as top level window => FAIL
    //
    // In the failing situations the viz widgets should really belong to different context groups (which
    // has it own implications), but as a workaround we can use the Qt::AA_ShareOpenGLContexts flag
    QApplication::setAttribute(Qt::AA_ShareOpenGLContexts);
