The drawing of Tiled Map is broken

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

pixel_border_fail

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?
