Final question on QQuickWindow vs QWindow Context

  • I've created a QWindow that is able to render my game window via my own QOpenGLContext

    When I change this window to a QQuickWindow I expected the same to be rendered.
    But when I change the class I get a quick flicker of my window and then I goes white as though something is over writing it?

    Could anyone tell me why?

    Edit: it has something to do with the scenegraph being rendered over my opengl window.

    I want qml on top of my window but I dont want to to clear it before drawing the scenegraph.

    I know there is a flag to turn off clear before rendering but that doesn't work.
