How to use QOpenGLFunctions with QtQuick in Qt 6?

[BitSpree]

Hello,

in our project we use QQuickFramebufferObject to render OpenGL contents in a QML UI. In Qt 6 this is no longer working with backends other than OpenGL. What is the best way to use QML on top of content rendered with QOpenGLFunctions in Qt 6?

Thanks for any advice.
