Pixel stretching on the UI

[scriptkiddy]

Hi guys I have a big problem with my UI button.
When I import the images (no matter PNG,PSD) , and make the image button - top pixel are stretched:(
I have tried almost everything. My images are perfect. On the Atlas texture as well.
Why is that? Please find the attached file.
Please help me.

Warm Regards
Sergey

This happens when you use a PMA shader with your atlas, and the atlas texture gets marked as "Alpha Is Transparency".

Turn off one of them.

There is no reason to use a PMA shader with your atlas right now. In fact, you had to have explicitly chosen "PMA Shader" option when making an atlas. It's off by default -- for this very reason.

Thanks again.
