    display: Compare configurations without monitor offset
    
    When comparing configurations, the monitor positions are compared
    directly. This comparison will not work properly if one of the
    configurations has an offset.
    
    This results in the "Apply" button to show up incorrectly after moving
    the top/left monitor position.
