Texture issue

Hi,

I’m currently working on a project with several trees in it.
Each tree consists of 2 polygons with some textures on it.
I’ve created 2 Screenshots that display the problem.

The first image shows my trees in the Editor-View:

The second image shows the trees after zooming out:

The second image shows a strange behaviour.
Some pixels of my tree texture are blue and yellow when I zoom out.

Can somebody help me with this problem?

Thanks in advance

Have you tried building the game and see if that still happens? Might just be the editor
