Same problem here. Mouse moves and I can swap to a different TTY but needs a hard reset to get going again.
Tried different graphic drivers and kernels but nothing seems to work.
Ubuntu 12.04 with Cinnamon 1.4UP3.
Froze when I was opening a PDF file in Evince (full screen).
I'm thinking it's a problem with Compiz. Does Mate use Compiz? If not and there's no problem with Mate, then it could quite easily be Compiz. That would explain why some desktops are effected whilst others aren't.

Hope this gets a fix soon :(
