    Description

      Changing images causes the UI to freeze and deadlock after  3 hours.

      The application code and dump file can check in the attached files.

      I have done some test cases as below:

      1. delete changing images, UI does not freeze
      2. change libQtcore.so, libQtGui.so, libQtQuick.so release version to debug version, UI does not freeze
      3. export QSG_RENDER_LOOP=basic, UI freeze
