                Windows Components > Remote Desktop Services >
                Remote Desktop Session Host'.

              connection will be broken by the server, as it usually happens in
              FreeRDP on other platforms.
            - WPS class: The negative coordinates of the window were
              incorrectly maintained. Fixed.
