Top down tile map visual bug

My current tile map works perfectly when I am managing it in the editor and looking at it normally. As soon as I look through the camera or start the game my tile map has a line through it where it looks like 1 pixel is from another tile. This is not a rendering issue where I made the art overlap because it only happens in one row not on every tile alike. Here is a picture I would really love some help!

The yellow and brown are not supposed to be there.

*EDIT* I found a way to fix this problem at least in my case. In unity the grid you are placing your tiles on has a tile size setting. Simply changed the tile size down by .001 and it got rid of every graphic issue since the tiles should be overlapped slightly.

 

This is quite common, it seems, to anyone starting out with pixel art or even the tilemap in general.

https://blogs.unity3d.com/2015/06/19/pixel-perfect-2d/ is a good resource to learn more about why it's happening.

You might also consider renaming your thread, now it is not very descriptive. "2D TILE MAP issues" could be anything related to tilemaps.

 

Thank you, this is my first post and I am getting a lot of quick help, really appreciate it. I will rename the thread ASAP
