Bug#1111117: gdm3: mismatched user avatar between login screen(s) and lock screen

[наб]

Package: gdm3
Version: 48.0-2
Severity: minor

Dear Maintainer,

I installed default-config Trixie (MATE),
then apt installed gnome and selected gdm3 as the greeter.
Please behold the login screens (where the user is a white guy on a grey background)
and the lock screen (where the user is debian).

Best,
