Look a the ears. They follow the character on this screen but they placement has bugged. Disconnecting and reconnecting solves the issues but sometime the placement get bugged by I don't know what. This seems to be affected only on the inventory GUI.
MC 1.12, Tails 1.10.0.

it occurs when you turn/move a lot, and open your inventory right after doing so

ik im not kihira but yea

Huh interesting.
Sounds like a value isn't being updated and it's stuck a tick behind.

It's a low priority issue though if it's only happening in inventory
