Since i’ve started working with tilemaps, i’ve notice that some weird lines pop-up during play test, these lines looks like the tilemap generates little gaps between tiles, they pop-up like a fraccion of second but there are lots of them all over the tilemap.

I hope someone knows how to fix this issue.
