Problem with Map and MapPolygon

  • Hi,
    I have some problems with the QML Map. I want to display specific areas like airspaces. I figured out, that the MapPolygon, which was created for testing, is doing strange things (vertical cuts, disappearing), if I zoom in until its borders are no more part of the visible area of the map. I'm using v5.5.1 but could also reproduce it with v5.6. How can I avoid this?



    import QtQuick 2.0
    import QtLocation 5.5
    Item {
        height: 600
        width: 800
        anchors.centerIn: parent
            id: osmplugin
        Map {
            width: parent.width
            height: parent.height
            plugin: osmplugin
            gesture.enabled: true
            id: map
            zoomLevel: (maximumZoomLevel - minimumZoomLevel)/2
            center {
                latitude: 50.348888888888894
                longitude: 10.918055555555554
            MapPolygon {
                color: "#550000FF"
                //Coburg - Germany
                path : [
                    { longitude: 10.918055555555554, latitude: 50.348888888888894 },
                    { longitude: 11.150833333333333, latitude: 50.2625 },
                    { longitude: 11.073333333333332, latitude: 50.17611111111111 },
                    { longitude: 10.840833333333334, latitude: 50.26222222222222 },
                    { longitude: 10.918055555555554, latitude: 50.348888888888894 }

  • Hi, and welcome to the Qt forum!

    I can confirm this behaviour with Qt 5.6.0 on x86_64 Linux with Nvidia graphics drivers. What is your platform?

  • @Wieland Thank you :) I've tested it on Windows 7 x86 64. Tomorrow I will check this on armhf with mali, but I'm not very optimistic :/ Any ideas, how to clean up the situation?

    No, sry. My hope was that we could blame the Nvidia drivers (again).

  • You can file a bugreport here:

    Thank you for testing :)
