Bug#948856: gdm3 screensaver issues in smartcard mode

[IB Development Team]

Package: gdm3
Version: 3.30.2-3

gdm3 in buster when configured for login with smartcards
in /etc/gdm3/greeter.dconf-defaults...

[org/gnome/login-screen]
enable-smartcard-authentication=true
enable-password-authentication=false

...has problem with unlocking shield screen - ESC button does not work there
(only on login screen, not user session lock screen). One must use mouse
to drag shield or press ESC just after mouse click...

In smartcard login mode there is also ugly screen blink just before
starting screensaver (dimming out) in gdm3 and in user session.

No such problems when smartcard login is disabled i.e.

[org/gnome/login-screen]
enable-smartcard-authentication=false
enable-password-authentication=true

Installation of newer gdm3 version from testing...

dpkg -i libgdm1_3.34.1-1_amd64.deb gir1.2-gdm-1.0_3.34.1-1_amd64.deb gdm3_3.34.1-1_amd64.deb

...does not resolve these issues.
