Tile Precision Error

While using Preview 4, I get seems in between my tiles at certain view points. This appears in-game as well and is quite distracting. I have the settings for my tile sheet texture attached; I have tried to change the wrap mode and filter mode to no avail.

 

I had similar issue. I disabled Multi Sampling from QualitySettings and the defect has gone.

 

Even though I disabled Multi Sampling, The issue recurred.

In my case, the glitched tile sprite violated the area alongside.


I solved this issue by setting NPOT tile textures to POT.
