I noticed the login screen occasionally greys out the login button (I assume waiting for user input).
However, when using a password manager, sometimes the manager fills out the form quickly (perhaps there's some kind of race condition going on) and the login button is greyed out despite the info being fully there.
I can get the login to be un-greyed by deleting a character from my username and adding it back in.
This is kind of annoying and seems like it could easily be fixed by just not disabling the button in the first place.
