Occasionally upon loading world, Armor Stands assume either the Wandering Trader texture or a texture sheet containing all the blocks in the game.

A few days ago I joined a Minecraft world with some friends, and needed to use an Armor Stand for some command block stuff. When I placed the stand, instead of the normal texture, it had the Wandering Trader texture. I flew around the armor stand and when I was at a different angle it switched to a texture containing all the blocks in the game in one sheet.

The player I was in the world with (FaintestTooth79) did not see anything unusual on their screen.

This glitch may be caused by resource packs, but it’s extremely unlikely since I had 2 resource pack on at the time in my Global Resource Packs: a pack that only changes the chat interface, and a pack that only changes the main menu UI.

The glitch disappeared once I left and rejoined the world.
