If you have the time to check the patch, any help is appreciated. Just load an image and toggle to switch between normal rendering and [pix_buffer]ed scene.

does the attached patch make any more sense to you?

Yes, indeed. I had only tried to change the size of [pix_snap] ignoring completely the [gemframebuffer] one and obviously got weird effects.

thanks! M
