I have the same problem and it has begun affecting me quite recently on an almost daily basis. Switching between to open Xorg-sessions seems to cause the bug and hangs the Xorg where one is trying to switch to. I can log in with ssh so the system is still accessible but keyboard and mouse are unusable.
