MapPolyline slow repaint problem

  • Hi. I'm creating navigation app. I'm drawing route that was already traveled with one color and route to travel with another one. I have problem that while navigation marker is moving fluently route is drawing with some delay. I'm updating polyline point on my navigation marker coordinate change:

       Connections {
                enabled: navigation.running
                target: naviArrowItem
                onCoordinateChanged: {

    When replacing polyline with MapCircle there is no problem with latency (circle coordinate change is instant).
    Maybe somebody know how to deal with this issue?
