While making custom textures of the stained glass for my Resource Pack I came to a problem, where the white, between my colours of the glass started flickering. I have no idea what I did wrong. It flickers every couple seconds from the translucent form it should be to complete transparency.
Not sure if related to the transparency bug I mentioned earlier:

Again I have attached screenshots and the Resource Pack stripped down to blocks only.
