[Interest] Scene Graph - Graph example background noise not appearing when OpenGL backend is used

[Nuno Santos]

Hi,

I’m taking as an example the Qt Scene Graph - Graph in order to pass a texture to a custom material.

However, if I use OpenGL as graphical backend by setting QQuickWindow::setGraphicsApi(QSGRendererInterface::OpenGL), the noise texture in the background does not appear. 

Is this example supposed to work if the backend is the default one?

Does anyone know the reason or the caveat here?

Thanks!

Regards,

Nuno
