      When resuming an Android application which uses the virtual keyboard, the application is frozen and does not respond to use inputs any more. There is no issue on resume when the virtual keyboard is not used at all. That effect can be reproduced each time, even when the virtual keyboard is hidden, as long as the keyboard has been shown at least once.

      The bug might be related to QTBUG-40750 and the generated traces is simular.

      Steps to reproduce:

      • Start an Android/Quick2 application using the virtual keyboard (e.g.: attached "mail.qml")
        application is not frozen
      • Put the phone in standby
        application is suspended
      • Switch the phone on
        application is resumed and properly responds to use input (not frozen)
      • open the virtual keyboard by clicking on the text field
      • (optional) close the virtual keyboard
      • Put the phone in standby
        application is suspended
      • Switch the phone on
        application is resumed but does not respond to user input (frozen!)
