Bug Description

In Kubuntu 20.04 after recent update from plasma-workspace 5.18.5 to 5.18.8, I am unable to unlock my screen by just typing my user password, as I was used to before. Now only a screen with a clock appears and no password textbox, there is nothing that I can do to activate the password textbox but to click somewhere with my mouse. The extra click with the mouse that is now necessary is inconvenient to me and a UX regression in my opinion, especially because I quite often lock my screen when working in the office.

Just reproduced in a clean install in a VM to rule out configuration cruft on my laptop. With plasma-workspace 5.18.5 it doesn't appear, on 5.18.8 it does, as shown in the attached video.

I also have this same problem with Ubuntu 20.04.4 and plasma-workspace 5.18.8-0ubuntu0.1.

I think this is caused by the following upstream bug:
https://bugs.kde.org/show_bug.cgi?id=439604

That bug is closed without a fix though, because 5.18 is unmaintained. However, there's another upstream bug about similar issue in:
https://bugs.kde.org/show_bug.cgi?id=449857

WORKAROUND / FIX

1. sudo nano -w /usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/LockScreenUi.qml
2. Comment out "enabled: visible" on line 234
