    When attempting to build and run one of the Qt Wayland compositor examples called the overview-compositor, I see some warnings in the Application Output tab as follows:

    Could not create scene graph context for backend 'opengl' - check that plugins are installed correctly in /home/simon/Qt/6.1.0/gcc_64/plugins
    qt.waylandcompositor.hardwareintegration: Failed to initialize EGL display. Could not get EglDisplay for window.
    

    A main window is then displayed with a Toggle overview button. This window is blank, and the toggle view button does nothing.
    Should the main window show something, or do I need to also start some client Qt apps?
    How can I get rid of the warning messages? I assume they are significant.

      Hi,

      You should add more information about your environment and how you are launching the example.

        The example does seem to work, even with the warning messages. I just needed to run a Qt application by calling from the command line with -platform wayland.
        I assumed that because of the warning messages it would not work.
        My environment is as follows:
        OS: Ubuntu 20.10 running in VMWare Player virtual machine on a Windows 10 laptop.
        Running from QtCreator 6.1.

          @lartimus could you find any solution for this situation. I have same warnings for d3d11 also. I can't find any solution for this.
