    sorry fat fingers. :)
    To the bottom. The scrollbar can be dragged more down to see the start of the call stack.

        Yes but it didnt show anything interesting.
        Do you call FullScreen any where ?
        seems to start there.

        Also, does other examples work ?
        Could be openGL setup that is messed up.

          @mrjj weird hmmm so i found the bit of code that was the cause!

              const QScreen* screen = qApp->primaryScreen();
              w.setGeometry( QRect(QPoint(0,0), screen->geometry().size()) );
              w.setWindowFlag(Qt::MaximizeUsingFullscreenGeometryHint,true);
          
              w.showFullScreen();
          

          but when i now run my App it's loading and "running" but no window comes up :S

            Did you remove the fullscreen or how did you make it run ?

            Try with
            w.show()

                Ok so it is when it tries to show the render surface.

                You have to try some of the openGl examples and see.

                I guess its your openGL since it seems to crash on showing.

                https://doc.qt.io/qt-5/qtopengl-hellogl2-example.html

                They are available directly in creator.

                    @mrjj i just noticed this

                    QQuickWidget is only supported on OpenGL. Use QQuickWindow::setGraphicsApi() to override the default.

                    could this be it?

                      Hi
                      yes it could very well as normally Desktop is using openGl and mobile some other ES? but
                      normally it's automatic.

                      This is a Desktop pc windows right ?

                      Did you compile Qt your self ?

                      Maybe its a Qt6 thing. try setting it to openGl via the setGraphicsApi as it says and then see.

                          Can it be that on startup some other API is set ?
                          Or you added some defines to .pro so it thinks its Android ?

                                Yes that seems perfect. should not interfere with which backend is used.

                                I cant tell either. Did you use any new Qt6 things ?
                                Could be fun to see if it does the same say in 5.12
