Border Artifacts/TileAnti-Alias pixels


i m using texture packer pro to pack my images however i m running into a problem of one pixel line around the borders of background images when they are combining and creating seamless scrolling.

I m using Starling and Scroll Image extension to loop background. When i have looped single images instead of sprite sheet there was no problem.

I have used every setting in texture packer including padding etc as suggested by some people having the same issue but seems no luck. Here are my problematic screenshots.
