    Description

      A minimal reproducer:

      Have the following code as "SubWindow"

      import QtQuick

Window {
    width: 400
    height: 300
    title: "Secondary window"
}

      Then instantiate it in Main.qml:

      import QtQuick
import QtQuick.Controls

ApplicationWindow {
    id: window
    width: 600
    height: 400
    visible: true

    Button {
        text: "Open secondary window"
        onClicked: secondary_window.show()
    }

    SubWindow{
        id: secondary_window
    }
}

      Run application and click button, a second Window pops up.
      In Qt 6.5.2: Geometry of the second Window is independent from the main Window. Moving/resizing the main Window does not influence the second Window by any means.
      In Qt 6.5.3: Moving/resizing the main Window weirdly resizes the second Window. The behavior is totally unexpected and may cause crash in certain circumstances (reportedly QWindowsWindow::savedDpi).
