    When running my app (Qt 5.12.4, QtCreator 4.9.2, Xcode 11.0) on an actual iOS device (iPhone XR 13.1.3), I get the following exception when closing the app (swiping up the app)

    Fatal: ASSERT failure in QIOSContext: "OpenGL ES calls are not allowed while an application is backgrounded", file qioscontext.mm, line 337
    

    Is this an application issue (ie. my fault somehow) or is it a Qt bug?

      If you hag googled with qt bug and the error message you would have found
      'ASSERT failure in QIOSContext: “OpenGL ES calls are not allowed while an application is backgrounded”'
