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.
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
