SUMMARY
The password field in sddm jitters or shakes whenever the password entered is incorrect. However, in our implementation, all of the elements on the screen, except the clock, will also jitter. This makes it a little odd given those are UI elements that are not being interacted with and don't add to the experience of entering the wrong password. It's also not recommended to make jumpy UI if we can avoid it. However, the jittering of the password field feels more appropriate and helpful.

Please consider making this change.
