Wierd chunk error does not dissapair

I was strolling around in my Single Player Survival game when a chunk error occurred. I have tried to log out, F3 + A, to check it in MC-edit(it's not a chunk error there) but it's still there! I do not know what to do about it?

I have a screenshot of my video settings, snooper settings, my F3 info and a video showing some of the weirdness of the chunkerror(really bad quality to fit the size restriction).

UPDATE:

Today I experienced that the chunk error duplicated 3 chunks to the south. This is quite annoying 'cause I sometimes have to use mcedit to get out of them because they are at my spawn. Do you have any fixes, using either third party programs or an in-game way?
