White lines on image png

Hi!
I’d like to ask you how to cancel white lines (see image):

There is png image on the back side (forest). This is the .blend file:

It’s really strange. I don’t understand why it appends, but a solution is to check “Full Sample” in the anti-aliasing settings. Unfortunately, it will increase the render time.

Oh, I found the issue. It’s because you’re using “Z Transparency” in the background material instead of “Mask”. Change only that and you don’t need to enable Full Sample.

Ok, thank you very much! I have another question: why in the background of the sky there are dark halos (see image):

You could reduce the texture crop maximum value for the y axis

Thanks, I think the problem has solved.
