I believe I am still seeing this issue (or one with the exact same symptoms) with lightdm-gtk-greeter 1.8.5-1ubuntu2~ubuntu14.04.1 on ubuntu 14.04
Upon boot, the first key press never works even though the password entry box has focus.
I also think others are seeing it and mistaking it for something else: http://askubuntu.com/questions/518675/first-password-often-wrong-when-unlocking-computer
