multiwindow scenegraph couldn't render correct

[mohammad sina msh]

scenegraph for rendering some 2d on qtquick and qml and i load my app from c++ with this code :

    QGuiApplication app(argc, argv);
    QQmlApplicationEngine engine;

#if QT_VERSION >= QT_VERSION_CHECK(6, 0, 0)
#ifndef QNANO_USE_RHI
    QQuickWindow::setGraphicsApi(QSGRendererInterface::OpenGL);
#endif
#endif

    const QUrl url(u"qrc:/NoroView/Main.qml"_qs);
    QObject::connect(&engine, &QQmlApplicationEngine::objectCreationFailed,
        &app, []() { QCoreApplication::exit(-1); },
        Qt::QueuedConnection);

    engine.load(url);

    return app.exec();

and

QQuickWindow::setGraphicsApi(QSGRendererInterface::OpenGL);

is for set graphics api for using on scene graph and its ok.
like this photo:

but when i opened another ApplicationWindow from qml

main window and second window that i opened gets into problem on rendering for example colors just show in green
and text doesn't show well
i designed an app using

and i think its because i cant setgraphicsapi for second window that i opened from qml with ApplicationWindow
