    • 9f5b96225885f927727a57b6123d8550d6c373bb (qt/qtwayland/5.15) 03e8c91fc28b77c4f027b6c6d582b85878efae41 (qt/qtwayland/5.12.6)

      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.
