I’m just gonna let the pictures speak for themselves.

Today I was playing Minecraft when I exited out of the app for a second or two. When I came back, no texture was right. I have a shader and a ui texture pack installed, but they don’t change any block textures (that I know of). I have had this before in 1.17.40, and this is the exact same thing. This was an experimental world with both the Experimental and Wild Update toggles. I couldn’t disable the texture packs without leaving the world because Mojang doesn’t believe in that, and I couldn’t exit the world and disable since doing that thing fixes this bug. There are a lot of unknown textures, so I’m pretty interested to see what Mojang has up their sleeve.
