The remote desktop is not locked with the native lock screen when the 'root' user is physically logged-in
After the client disconnects, the physical desktop is locked with a screen saver requesting for credentials of user 'nx' instead than with the native lock screen. This happens when the local user is physically logged-in to the system as 'root'.
This problem has been reproduced with NoMachine on SLES 12, GNOME Version 3.20.2 and xscreensaver v. 5.22.
SOLVED, Released in version 8.9.1
