    Description

      Easily reproduced with any qml that lets the PinchHandler directly manipulate the target, e.g. qtdeclarative/tests/auto/quick/pointerhandlers/qquickpinchhandler/data/pinchproperties.qml : pinch once, release, then pinch again. The scale jumps when the new pinch gesture starts. It's not a problem on touchscreens, only on trackpads that generate a QNativeGesture (macOS now, Wayland soon).
