Placing a Scene3D in the demo.qml from the "rendercontrol"-example, does not show the Scene3D and results in the following output:

Qt3D.Renderer.Backend: bool __cdecl Qt3DRender::Render::GraphicsContext::makeCurrent(class QSurface *) makeCurrent failed
Failed to make OpenGL context current on surface
QOpenGLContext::swapBuffers() called with non-exposed window, behavior is undefined
