iTween: CameraFadeAdd Texture issue

Hi

I'm using iTween.CameraFadeAdd(cameraTexture, 0); to add a texture to a camera in Awake(), which I then fade out at opening of a scene to create a fade in effect using iTween.CameraFadeFrom(1,1); in Start();

This works fine, however, the texture when appears on the screen, appears to be about 1 pixel off from the top of the screen.

The texture itself is 1024 Compressed (Best) With Repeat wrap mode.

Anyone have any suggestions how I might rid of the line at the top of the frame?

Thanks
