Hard to tell by the image, but it looks like some texture artifact.

In any case, it might be, that the outer most pixel is bleeding over the edge and gets repeated. You can set the texture wrap mode to clamp. Maybe you even need to leave more space between the edge of the image and the actual pixels. If it's a sprite, you should set the type to texture.

Thank you, non-transparent pixels were right next to the margin of the image (the empty space was cropped), so when I left a couple of extra pixels margin, it looked perfect.

The texture wrap mode was already set to clamp and it wasn't a sprite, it was a cookie texture
