Can't use Office2016 style while disabling AA_DontCreateNativeWidgetSiblings

If I disable AA_DontCreateNativeWidgetSiblings, the rendering problems go away assuming I have also turned off the Qtitanribbon Office2016 style. If I leave the Office2016 style on and disable AA_DontCreateNativeWidgetSiblings, then the Ribbon UI hangs on startup.

But we have to use the qtitanribbon Office2016 style(or some derivative of it that we create for our specific purposes) to properly display the ribbons.

Unfortunately, we can't reproduce the issue by your description. We have commented out AA_DontCreateNativeWidgetSiblings here:

MaterialWidget::MaterialWidget(QWidget* parent, Qt::WindowFlags f)
{
...
//qApp->setAttribute(Qt::AA_DontCreateNativeWidgetSiblings);
}

Office 2016 style works as expected.

Thanks for the response. If I disable the creation of our main OpenGL window on startup, the hang goes away. If I later click a button in the UI to create the OpenGL window, everything appears fine. So I know it's related to the creation of the OpenGL window.

We trigger the creation of the OpenGL window on startup via a singleShot QTimer event. It was set to 0 second delay. I changed it to a 10s delay for testing and the hang is still there. There's someting problematic about the singeShot event. Any ideas?
