Do you also get this in the top-right corner? http://i.imgur.com/LPiKgdO.jpg

I have the exact same problem when I log in quickly after startup. I have to count to 10 after booting to the login screen and then I can login without freezing. I also use LightDM, so I don't know if maybe this issue would go away if we used gdm.
