    Hi all,
    I'm trying to use OpenGL with a QGraphicsView.
    It seems that to get "benefit" of opengl support using a QGraphicsView you only need to set a viewport as the following code:

    QGraphicsView view(&scene);
    view.setViewport(new QGLWidget());
    

    so I'm trying with Colliding Mice Qt example to start from a working small project.
    It works fine on a Linux desktop PC.
    The main target of my test is to start the application using EGLFS platform but there is a problem. When I start the application as:

    ./collidingmice -platform eglfs
    

    I get the following error:

    EGLFS: OpenGL windows cannot be mixed with others.
    Aborted
    

    Is it a BUG or is there a solution?

    Thanks

    Luca

      Hi,

      I may be wrong but based on this, it seems to be an unsupported use case for EGLFS.
