Xenial Mate: Screensaver Preview & LibreOffice Slideshow problems
We'll take these one at a time;  although, they are related.

... first, I have reproduced the anomalous behavior;  for which there is one more related glitch-- namely if the check-box is selected on the screen-saver panel ( under preferences look and feel ) "lock screen when screensaver is active" then when the screen saver runs the machine locks and apparently will not allow you to unlock it !!

Not true, at least for the second part;  even though there is no "unlock dialogue"  if you enter your password the screen will unlock...   obviously remove the checkmark to lock the screen when the screen saver becomes active. 

This will not work on the glitch you reported...  but the following will ( although, its messy ).

1)  press  ctrl + alt + F1   to pull up our dearly beloved fbcon.

2)  logon 

3)  start htop with :

         sudo htop

4)  find the lightdm top process;  you might need to configure htop to display in tree view;

5)  select the lightdm process with the cursor and press F9  (defaults to SIGTERM which is what we want)

6)  press the Enter key
         ( the desktop processes will all die )

7)  on the lightdm  logon panel -- Logon

... We'll talk about the rest later .

Note :  I've also had this same behavior happen when the screensaver triggers with the settings panel open !   Its a PITA because then I have to go out and kill the lightdm again and start over;  really needs a reboot.

We need to find out if there is an upstream bug report for this, and if not report it.

Note:  To emulate the screensaver bug ( but without locking up the whole lightdm ) click the System --> lock screen

...  the screen will lock, but you'll be able to move your mouse around;  nothing else will work.  If you move the mouse ( or type a key ) the unlock dialogue will NOT appear !  ... try it  press some keys !  

... to unlock the screen press the enter key ( tries to unlock and clears the buffer ) then type your password and press the enter key;  the screen will unlock--  never does the unlock dialogue appear !
