    Description

      When setting 

      Material.theme: Material.System

      on Ubuntu 20.04 with Dark Mode enabled, qml does not seems to recognize that the system is in Dark Mode.

      To reproduce:

      ApplicationWindow {
    width: 640
    height: 480
    visible: true

    Material.theme: Material.System // set in qtquickcontrols2.conf

    Label {
        anchors.centerIn: parent
        text: Material.theme === Material.Dark ? "Dark" : "Light"
    }
}
