      In the attached example the following warning message is shown every time the user clicks on the window (running inside pure-qml):

      qt.qpa.wayland.backingstore: Delivering update request through fallback timer, may not be in sync with display

      The code changes the opacity of the "sign" element on every click and uses a behavior to animate it.

      The warning is only shown when the "threaded" render loop is used.
