Created attachment 113666 [details] Since the stupid bug tracking system only allows one attachment, here's a tar gz of two poorly taken pictures with my phone since I hope I can't actually screenshot the lock screen No primary display chosen in settings manager. I have a laptop with a built in display that correctly obscures the characters entered for the password, but the other display, an HDMI a connected Sharp television, shows the characters in plain text. The behavior started happening randomly, possibly after an automatic package update. I am not sure, what caused it, and I am not sure if a reboot will fix it as I am tying this up before rebooting. I will keep the system in this current state until I can help debug what's happening, unless someone doesn't get back to me withing 24 hours. Pictures of the behavior are attached.

Yikes, that's bad. FWIW, SDDM is the login manager; kscreenlocker is the lock screen. So you're using KDE Plasma 5.12?

Nevermind. Apparently, I filed the original report and forgot. Oops.
There's a "show password" button to the right of the textfield, that due to various reasons doesn't render an icon. I suspect you are clicking on that, which isn't surprising given the icon is invisible. I should probably just remove that button given that icon hasn't got fixed.
Git commit 505ce9929b2f36d8e29330f0accfbb83d654a8cd by David Edmundson. Committed on 15/01/2020 at 10:43. Pushed by davidedmundson into branch 'master'. [sddm-theme] Don't have a broken reveal password button Summary: sddm-greeter will have a button for the reveal password button, but due to sddm-greeter not loading a relevant QPT has no code to force it to load the breeze icon set. Without the breeze icon set, the clear button does not show. There are ways to solve this, but none are trivial or reliable. I threatened to do a revert in 5.12 (https://phabricator.kde.org/D9040) but the bug has still not been fixed since.
