There are a lot of glitchy textures including Diamond Block, All wool and carpet, Dirt, etc..
So there are glitchy textures, I suppose from using non-marketplace textures, but some of the affected blocks are: Dirt, Dead bush, Diamond Block, Daylight sensor, L. Gray carpet, varieties of wool/ carpet, etc.. They mainly are glitched to look like weird repeating command blocks, but some(carpets) look like smokers and magma blocks (both augmented ) and It really interferes with my Minecraft experience. Please fix, this is a bad texture bug, thanks.
