Map Visual Glitch

I've been trying to reproduce this both in single player and split-screen games but without any luck. Is this happening in all your worlds, or only this one? Are you able to take/post a video showing a full zoom in/out from min to max and back so we can see when at what point it appears and disappears?

There are two videos showing the glitch in the above world, and one showing the glitch in the caves. The one in the caves is different, as that just seems to be map shroud that has somehow returned and it can be explored again.

This is only happening in one world, which happens to be the most advanced. I have tried to reproduce it in other worlds that are not as advanced and it does not exist. I think that the next more advanced world I have, I abandoned it right before the Pirate monkey update. 

The glitch also is present on split screen or single player. 

 

On second examination, it looks like the glitch starts and continues after a zooming out to a certain degree. 

I have this too

I may have found the problem, will try to fix it for the next update
