Your texture seems to be 1 pixel short on 2 sides. Zoom in on your texture, and you will see a very small white edge. You can just fix this in photoshop, or even in paint.
Ok yep i found the white line in my texture my bad.
by the way, interesting how the textures are layered out on the skybox cube that it displays that white line in such a way since it is only on the corner of 1 of the textures XD
Thank you for the fast replies though!
