SDDM screen with taskbar

SUMMARY
This has happened a few times since 5.19 was installed.

Occasionally the taskbar from the user i logged out of gets loaded on the SDDM login screen.  I can click on Firefox and it will load my logged users' set up with all the correct tabs open and i can use it.

STEPS TO REPRODUCE 
1. Login 
2. do some work
3. logout via applet and then the next screen that appears and click logout again.

OBSERVED RESULT (not every time)
Log out, SDDM login screen gets displayed and so does the usable taskbar

EXPECTED RESULT
Log out, SDDM login screen gets displayed

I've also ex[rinced a full desktop after logging out and leaving the screen to go into screen saver mode at the login prompt.  The only way out is Ctrl,Ctrl,Backspace and then reboot which clears things for a few login sessions.
