When using Qt Quick Controls and using QGuiApplication instance, the popups (i.e. ComboBox) are misplaced if Qt::AA_EnableHighDpiScaling is set.
This is reproducible with gallery example by making 2 changes:
- Change the example to use QGuiApplication instead of QApplication
- Add AA_EnableHighDpiScaling flag
The issue does not reproduce when QApplication is used. Controls 2 does not suffer the same issue even when using QGuiApplication.
