Pinch gesture does not work

XMLWordPrintable

    • Windows

      On my Windows system a 2-finger pinch gesture does not work and following warning occurs: 

       qt.quick.touch.target: during delivery of touch press, synth-mouse ID 2000001 is missing from QQuickPointerEvent(1773 dev:TouchScreen [QQuickEventPoint(accepted:false state:Pressed scenePos:QPointF(254,177) id:2000002 timeHeld:0) ])

      I attached a simple test, but it is reproducible with Qt examples too (see Examples\Qt-5.13.0\quick\touchinteraction\pincharea)

      I turned on some debugging categories (qt.quick.touch qt.quick.touch.target), see debugOutputs.txt

      The same bug was already mentioned at the end of QTBUG-74008

      I opened a new bug report as suggested there

      In Qt 5.11.1 the pinch gesture still works, seems it got broken in 5.12.x
