probleme size window with UWP compiler

Guigiidre

Hi all I 'm facing a strange behaviour when I try to run a code with a UWP compiler.
My code is:

    QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);

    QGuiApplication app(argc, argv);

    const QString mainQmlApp = QStringLiteral("qrc:///main.qml");
    QQuickView view;
    view.setSource(QUrl(mainQmlApp));
    view.setResizeMode(QQuickView::SizeViewToRootObject);
    view.setPosition(0,0);

    view.show();

and main.qml

Rectangle
{
    id:dialog_dongle
    objectName: 'popup'
    width:200;height:200
    border.color: 'blue'
    border.width: 1
}

with the mingw compiler I have this result that is ok:

and with the uwp (MSVC 2015) I have this:

It seems that in the last case the QuickView is inserted in another window. What is wrong ?
What do I have to do to achieve my goal and have the result showed in the first picture with the the UWP compiler ?

Thank ,you in advance for your answer.
