This is only reproducible on ARM64 having OSX11

Attached little example which can be used to see setGeometry is not working as expected with multiple screen setup. Follow the step below:

1. Use two screen in vertical layout, primary one (macbook screen) below, Secondary screen above
2. Position parent window in Secondary screen.
3. Close primary screen but keep Secondary screen still in use.
4. Reopen primary screen.
5. Open child window and use setGeometry to position it, and this does not works
