Problem is landscape generation becomes very slow to the point of refusing to generate at all, I can go back to where I came from and move around pretty much ok but the problem area will remain a problem until I quit and come back.
I have noticed that when the problem is happening, my cpu is working flat out 100%. When the problem is not there cpu usage is much less averaging around 20-30%.
I tried making a new world in version 1.1.3 and it was ok until I decided to travel a long distance to find a woodland mansion then the problem started again and worse than ever to the point where I can not get back to my original home.

I have noticed that it mainly happens when I travel by boat. After a short distance scenery will begin generating slowly and movement of arms and paddles become unsmooth and cpu is at 100%.
If I then turn back to shore and get out of boat onto land, movement becomes smooth again, scenary genertes ok and cpu usage drops to 20-30% max.
This is a very disabling problem to the point where I cannot play the game anymore and it has been going on since version 1.1. I have tried piggy backing on a report (mcpe20174) which is similar but I'm not sure if anyone is taking any notice as that report is marked as resolved. Please help.
