Extrude the borders of your tilesource.

You only need 1 if you know you are not going to be doing any scaling of the tiles. 2 if you do wish to scale the tiles due to mipmap scaling.

There’s an explanation to what happens in the note-box here: http://www.defold.com/manuals/2dgraphics/#_creating_a_tile_source
