I have the same problem. I noticed thought that the flicker seems to coincide with the appearance of the "Enter Password" text. It's already focused when the screen first arrives, then the screen flickers and focus is lost. Could be a coincidence, but thought it might be helpful. Can anyone else confirm that?
Running Arch Linux: tried both the lightdm-gtk-greeter (Arch repo) and lightdm-gtk-greeter-devel (AUR) packages.
