[Mixed monitor resolutions] QQuickWidget dialog window will cut off content when shown on mixed resolution/dpi monitors.

Setup:

Have two monitors with different scaling or dpi settings.

• Monitor 1 (main): Standard resolution screen (e.g. 1920x1200) or 4k screen with scaling set to 100% (windows display settings)
• Monitor 2: 4k screen at 200% scaling (windows display settings)

 Scenario:

An application which shows a QQuickWidget based dialog containing a loaded QML file. (See attachment)

Expected: The dialog is sized correctly on either screen.

Actual result: When the application is started on the second (full 4k) monitor, the window and dialog are too small and content is cut off and not visible. This is mostly an issue when a user plugs a 4k screen into their non 4k laptop.
