Animals Glass Panes

[TheDarkProgram]

The only animals I have tested are the pig, cow, and horse and if you are on a glass pane and you open your inventory you start glitching out and shaking/spinning.

They also do it on fences

It's basically any mob that glitches out while the game tries to render the player in the inventory. I've experienced this with Hats as well, so it's more of a vanilla issue.
