Everything in the new breeze sddm theme in Plasma 5.8.0 is centered on the screen. But when I start typing my password, the text is left-aligned in the password text field; this really does not look good. The same holds for the username field, if the user chooses to log in as "another" user. I propose that the text on these two fields be centerer. Reproducible: Always
If this is ever implemented, the change should also be applied to the lock screen, where the password field is also left-aligned currently.
In both the login and logout screen we're using a generic Plasma component for the input field: https://api.kde.org/frameworks/plasma-framework/html/classorg_1_1kde_1_1plasma_1_1components_1_1TextField.html If we change the text to be centered we're creating an inconsistency. I'm also not don't know if it's doable. And I've also not really seen lock and login screens with this sort of a behavior. Nate, what do you think?
I don't really think we should do this. As you've said, nothing else has the proposed behavior. It would feel weird and I guarantee that we would get bug reports about it. Sorry. :)
