I am very very very very very very very new to shaders. What i am trying to do i simple copy a mask from one image to another.
My shader looks like this and i'm rendering to a quad;


My problem is if i copy the mask from imageA to imageB and then imageB to imageC and ImageC to ImageD etc the alpha mask degrades.

This is my initial image



And this is the image after a few iterations (Notice how the edges are all fuzzy)
