Ui components are behind Status bar (top) and Navigation bar and cannot be used. See images: bars.png, side-slider.png
Workaround, change to landscape and back to portrait. After that view is positioned correctly below and above Android system bars.

Same problem occurs on other examples too, more or less pronounced.
Especially affected Examples:
Qt Quick Controls
Wearable - Cannot go back from sub-view without exiting the app.

Tested with Google Pixel 6a
