My biggest complaint is Grub. It now has an icon to the right of the password entry which toggles between black dots to plain text for password entry. No way I even want the possibility of my password showing up.
Hopefully there is a configuration entry some where to fix this. If not lightDM here I come.
Here is a description. Bad move in my opinion.
Any part of the GNOME Shell system UI that lets you enter a password (e.g., permission prompt, Wi-Fi network password, etc) now has a visibility toggle in the password field. This lets you ‘peek’ at the password you enter to double-check it’s correct.
EDIT: Worse than I thought, same thing in the permission window for GParted and other permission windows. So going to lightDM won’t fix the problem.
