The Illager banner, when applying the Chroma Hills HD resource pack renders glass (block, pain, any colour) completely invisible behind the banner, in bother 128x & 64x.

This is reproducible in either Creative mode or Survival mode.

This issue in not affected in other resource packs (that I had installed to test), nor without resources packs installed (vanilla).

Nor is it an issue with other banners and item/block with transparent area on them, as an example in the images: hoppers, doors, etc.

I'm not aware (at the moment) if this is an issue in or has been address in later beta versions.
