Sometimes when I open the game or join a world, random textures swap, merge, or just completely break.
From what I’ve seen, this only effects animated textures, ui, and the player's skin.
All screenshots were taken in a completely vanilla world, with no resource or behaviour packs active.
You may have to relaunch the game a couple times to get the textures to swap.
