How do I fix this tilemap issue?

Hello! Could you help me?

How do I fix this? There's 3 tilemaps of mountains composing a paralax effect on the layout. But there's a line that appears on preview and it's exactly on the upper line of the tilemap box.

I'm sure there is no such line on the image.

So, why is this appearing? How do I fix?

TileMap or TiledBackground?

With TiledBackground this can happen if your TiledBackground object is 1px taller than the image. For example, image height is 100px and TiledBackground height is 101px. Or maybe there is a semi-transparent line at the top edge of the image itself, try cropping it. It's hard to guess without seeing your capx.

dop2000 Sorry, it's a tiled background. My mistake.

The image size is the same, and there is no transparence.

I'll send the capx soon.

A common issue is that because tiled backgrounds repeat the image and can be displayed at fractional positions, sometimes the bottom part of the image wraps around and appears faintly along the top of the object. Adding 1px of transparency at the bottom of the image usually fixes this.
