Comment # 1 on bug 1200235 from Sebastian Kuhne

Many thanks Frank for this excellent description.
I can confirm a similar behaviour.

My use case based on your description structure:

*steps to reproduce*
(1) log in user1 with 'Desktop Session: Plasma (Wayland)'
(2) chose 'switch user' in user1 session
(3) log in user2 with 'Desktop Session: Plasma (Wayland)'
(4) chose "log off" (abmelden) in user2 session

*expected behaviour*
log off user2, prompt for user1's password is displayed, user1's password can
be typed, session of user1 can be continued

*observed behaviour*
log off user2, prompt for user1's password is displayed, user1's password
CANNOT be typed, no mouse click is accepted, session of user1 CANNOT be
continued.

*notes*
(1) Bug reproducible 100% with Desktop Session Plasma (Wayland)
(2) Bug NOT reproducible with Desktop Session Plasma (X11)
