Scrolling of ScrollView is not smooth

    XMLWordPrintable

Details

    Description

      Looks like the issue happens because of QQuickWheelArea::wheelEvent, this method is called approximately every 20-30 milliseconds during the scrolling and sometimes calls are missed (so delay increases to 40+ milliseconds) while ScrollView's contentX/contentY properties should be updated every 16 milliseconds for smooth animation.
