The password box doesn’t show unless mouse is moved
When I unlock screen, the password box does not show immediately.
With gnome-screensaver, it was enough to press any key on keyboard, and the box would show up and the key would be interpreted as the first character in the password.
With gnome-flashback, I have to move mouse/touchpad first, pressing keys does not make the password box show.
Please either let the password box show immediately, or make key presses show it.
