I think I have this bug too; for a while I thought it was due to ecryptfs because it happens very frequently while I'm switch message in Mutt, and last time that was happening it was ecryptfs related, but because the screen quickly stops updating and I can use the SysRq key to reboot. I didn't have access to another computer to SSH into mine the last time this happened, but I will check when this happens again and confirm whether this is a GPU hang. I do see that CapsLock doesn't work anymore after the hang which is why I thought my system had completely frozen -- but thinking about it, it could be that the xorg events dont get delivered anymore.
