Weird line above foliage

I created my own grass texture in photoshop, imported it into my project, created a material and applied it to a mesh, however I am getting these lines that appear above the mesh. It looks like there is a line of pixels appearing at the top and I am not sure why.

Things I have tried:

  • Using a PNG

  • Using a Targa with my own Alpha channel

  • Clamped the texture so it down not tile on both axis

  • Testing other grass textures, which worked fine.

If anyone can help that would be greatly appreciated!

I believe that I have fixed it, even though I had clamped the texture the bottom of it was still poking through at the top. So i masked out the bottom of the texture in the alpha channel in Photoshop and it was fixed.
