file shot showing 1fps, it seems to be facing south, facing north it doesn't happen
I have this too from a 1.8 created world, and I assume it is responsible for making the fps go to 0, it was fine until c snapshot, now when I go to this area the fps drops to 0 or 1 and makes the game unplayable.

yes I have this problem too, but my world is a 1.8 world that didn't appear to do this in the previous 2 snapshots
I have a similar issue where the screen just freezes goes to 0 fps and occasionally goes to 1fps, only way to get out of it is to esc and move the mouse, pressing esc doesn't work by itself.
