If you use the default value (True) for the show_border property, the border is drawn always in the bottom left corner of the app window (not taking the position of the QRCodeWidget into account).
Workaround: Explicitly set the show_border to False.
To fix it, the canvas Line instructions in the qrcode_widget.kv file have to be amended to add the current position of the root widget.
