The drawing of Tiled Map is broken

When I view a map created with TiledMap, the pixel boundaries are not drawn correctly.

Pixels adjacent to the tileset grid are drawn finer.
Parts that are not adjacent to the grid are drawn correctly.

The display collapses when making a pixel game.

Is there a way around this?
