If password checking takes too long, the UI behaves as if the password has been rejected - but then it unlocks the screen.
do you get a password failed message? It's intended behavior to block the UI from further input while the password is being checked. That is the input field gets disabled and only re-enable once the password is evaluated.
No, no password failed message. But I don't think I ever get a password failed message anyway.
sorry, but this looks like intended behavior: https://quickgit.kde.org/?p=plasma-workspace.git&a=blob&h=03ac02149ca8c7db133c42aa39fd7f9d946dda51&hb=a56f6c9d98197541663713978d5a754fa667a15a&f=lookandfeel%2Fcontents%2Flockscreen%2FMainBlock.qml#l99 While the password gets verified the input field is disabled and after a timeout of 3 sec the password field is cleared and enabled again. I don't see a bug there. The better question is: why does checking the password takes so long in your case that it hits the boundaries of the safe guards?
