The first one is quite normal, but the second one is kind of strange. It has black gnome3-style panel at the top and Debian wallpaper (like this: http://orig14.deviantart.net/ef84/f/2014/230/9/4 /debian_wallpaper_by_takaju-d7rr1sn.png). Both accept my password but, after the second unlocker the cinnamon panel disappears. It becomes, say, invisible. The start button (on the keyboard) works and Alf+F2 works but I have to restart the computer to get the normal cinnamon look back (ctrl+alt+esc doesn't help).
