Use of QML Map component with OSM, Esri plugins freezes UI

    XMLWordPrintable

Details

    • Linux/Wayland, Linux/X11

    Description

      Using a Map component in a QML application freezes the UI and locks up the app, forcing the user to kill the process.

      This happens when new tiles need to be loaded in; upon opening and reopening the map, more tiles will appear before each crash, until enough are loaded to allow the user to move around and zoom until new tiles need to be loaded, leading to further crashes.

      This afflicts both OSM and Esri map plugins. Curiously, this does not affect the MapBoxGL plugin - maybe due to a different rendering method?

      Would appreciate any insight on a fix/workaround. Thank you!

      EDIT: This is the console output:

      QObject::connect(QQuickWindow, LocationMap_QMLTYPE_0): invalid nullptr parameter

QGeoTileProviderOsm: Tileserver disabled at  QUrl("http://maps-redirect.qt.io/osm/5.8/satellite")

      Here is the QML code:

      import QtQuick 2.15
import QtQuick.Controls 2.15
import QtLocation 5.15
import QtPositioning 5.15

Map {
    id: map
    anchors.fill: parent    
     property alias pluginComponent: mapPlugin    

    //center: QtPositioning.coordinate(0,0)
    //zoomLevel: 15
    gesture.enabled: true
    plugin: Plugin {
        id: mapPlugin
        name: "osm"
    }
