Maybe should be added that it affects both Vanilla texture packs.

--------------
As the title says and the screenshot shows.

Hasn't been in 19w40a.

It affects both the new textures, as well as the "Programmer Art" texturers, albeit they look differently.

New textures

Old textures

Also affects other textures, willl create bugposts for each of them.

I searched for "barrier", sorry if I may have overlooked it.
