I have switch user function from the application menu which functions to take you to a new login screen showing list of users, and options; Switch to This Session, Start New Session, and Back. Choosing the Switch to This Session option results in session hang on an empty screen with the wallpaper and mouse pointer (same as described in comment 27). Start New Session, and Back both work as expected.

I do not have any options on the lock screen to Start New Session or Switch to This Session.
