    Description

      Using either a PinchHandler or a PinchArea in the QML code (rendered by QQuickWidget) zoom in/zoom out with pinch gesture is very jumpy. Here is an output of the scale values:
      qml: 269.53197334482996
      qml: 268.2647536136127

      This problem doesn't occur when using Qt 5.15.1. I've attached a minimal example.
