2D toolkit Scrambled textures when changing textures in a sprite ?

Hello everyone my team recently changed our UI tool for NGUI to 2D toolkit, while it is useful we are having a few issues with the final integration aspects, namely dynamically populating an image that should hold a saved screenshot.

this is my image as it appears when I set the main texture in the renderer component on our sprite

When I look at the image in the inspector though it is perfectly fine . does anybody have any suggestions or hints on what I may be doing wrong that causes the image to come back so scrambled ?
