    Description

      When having a simple qml application that has Window and a Text element in it, switching Android's navigation mode between buttons / swipe gestures hides the Text element, and makes the window Title visible.

      This happens only on Android 12, on SDK 31+. Does not reproduce on a device running Android 11 and SDK 30.

      Attached before and after images of the issue.

      Reproduce steps:

      • Run attached sample
      • Go to System -> Display -> Navigation bar -> Toggle Buttons / Swipe gestures
      • Go back to application

      Expected: Application looks the same
      Actual: "Hello world" text is missing, and title bar is visible on top
