most pixel-effects (that allow it) di image-manipulation _in place_ . 
this means that the (left side) image of an effect is overwritten.

this explaings why your "source data" changes as well.
you can use [pix_buf] to decouple the image source from the effect.

apart from that, ben is right, that Gem is probably not the best 
available platform for such kind of things.
