Description
This minimal_map example, with qml like this:
import QtQuick import QtLocation import QtPositioning Window { width: Qt.platform.os == "android" ? Screen.width : 512 height: Qt.platform.os == "android" ? Screen.height : 512 visible: true Plugin { id: mapPlugin name: "osm" } Map { anchors.fill: parent id: map plugin: mapPlugin center: QtPositioning.coordinate(59.91, 10.75) // Oslo zoomLevel: 14 DragHandler { id: drag target: null onTranslationChanged: (delta) => map.pan(-delta.x, -delta.y) } } }
works as expected but if the Map is placed in a Layout, like this:
import QtQuick import QtLocation import QtPositioning import QtQuick.Layouts Window { width: Qt.platform.os == "android" ? Screen.width : 512 height: Qt.platform.os == "android" ? Screen.height : 512 visible: true Plugin { id: mapPlugin name: "osm" } ColumnLayout { anchors.fill: parent id: layout1 Item { Layout.fillWidth: true Layout.minimumHeight: 10 } Map { id: map Layout.fillWidth: true Layout.fillHeight: true plugin: mapPlugin center: QtPositioning.coordinate(59.91, 10.75) // Oslo zoomLevel: 14 DragHandler { id: drag target: null onTranslationChanged: (delta) => map.pan(-delta.x, -delta.y) } } } }
panning suddenly becomes choppier, and horizontal dragging makes the map also pan vertically.

Update: After logging out (to try X11) and back in everything seems smoother, but the vertical panning is still there:
