How to remove the line above the tiled background

I'm creating this post to provide a solution to a problem I had, but the posts I found were too old to even comment on.

The problem:

I'm using a blocky background to create a parralax effect, but a 1-pixel black line appears on top, and it's not something from the image I used.

The solution:

Using the crop button and adjusting the image size perfectly makes the line continue to appear in the layout, but when executed it no longer appears.

I also noticed that changing the sampling type can solve the problem.

I hope this solution I found can be useful to someone.

I have also seen that annoying black line on some sprites when running the game.
