Unity spriteAtlas bugs issue?

I am using Unity SpriteAtlas.

There are issues.

The sprite is not clean and the image residue on the side is buried.
Could this happen because the resources are not of the correct size?


After the build, the image changes vertically or horizontally.
If any of these issues arise and you know the solution, please answer them.

Have a nice day.

This is an unresolved issue in 2018 3.0 b12.
In addition, no error message is displayed even though the size of all sprites exceeds Max Texture Size.

Please answer this post.
