I've noticed that when this happens, if a text box was selected before closing my laptop's lid, when I open up again and try to enter in my password, it's entered into the text box, instead of into the password field. Needless to say, that's an incredibly disturbing behavior, especially when the text box behind the lock screen is an instant messaging service! This bug has, for whatever reason, just started to affect my system (an up-to-date Ubuntu 14.04 system) over the past day.
