I am experiencing the same problem switching between two users using gnome. I cans witch to the second user just fine, but when switching back to unlock the first user session, the enter password screen is all white. I can unlock by typing my password and hitting enter but it took me a while to figure this out and was very confusing at first. I'm including some info that may be useful:
