This is a regression bug that happened between 5.12.4 (correct) and 5.12.5 (wrong)

In the following configuration, everything works fine when creating a QAxWidget on a main display. However, when you move the app window to the secondary
screen and then create the QAxWidget, it does not render at all.

    SetProcessDPIAware();   //make System-DPI Aware
    QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
    QCoreApplication::setAttribute(Qt::AA_UseHighDpiPixmaps);
    QCoreApplication::setAttribute(Qt::AA_DontCreateNativeWidgetSiblings);

How to reproduce
0. You need two displays and one should be 150% scaling for the Qt High DPI scaling to kick in.
1. Use Qtbug96114.zip
2. Press "create Ax Widget" button in the main display -> Qt Ax widget is created and WMP is shown
3. Move the window to the second display
4. Press "create Ax Widget" button

Expected result : Qt Ax widget is rendered
Actual result : Qt Ax widget is not rendered
