I can confirm this bug on another Distro. Using Arch with Gnome 3.12 and Nvidia GeForce. The lock screen is frozen, mouse cursor visible and movable but UI does not react. Keyboard input works, but has no "visual effect", I can switch TTY and type commands blindly but the lock screen remains frozen.
