Package: gdm3
Version: 3.20.1-1
Severity: normal
Dear Maintainer,
once every 200-400 logouts, the next user can read his password while typing.
If login button is pressed using a wrong password, the next login attempt works
correctly (characters can not be read and are represented as dots).
I was expecting passwords to never be readable.
