Okay, I recently saw this in someone else's realm. It's where you have sized your realm so that the floor level is one block above bedrock. A lot of people do this to give themselves the maximum amount of space to work on. What happens when this is done, is if you fly up into the air, it adds these ugly lines across the floor of the map.

This of course is a problem if you are trying to take a screenshot of it, or video of it.

But, don't fret. I have a solution. I have created a clear bedrock image, that gets rid of the lines completely. No matter how high you go or how you look at your realm, the lines won't be there. That image is attached to this thread.

Your Welcome and Goodnight!
