I'm using a MYPHONEMY27 Android phone.

When placing too many items or building too much structures, there is a chance that TAMED HORSES, DONKEYS AND MULES WITH SADDLES produce a weird texture glitch.

How To Reproduce:
1: YOU MUST HAVE A TAMED HORSE WITH A SADDLE ON IT in your world, preferably having it tied to a fence.
2: Build random things, preferably structures using pistons, sticky pistons, and redstone-type blocks.
3: Trap a couple of tamed donkeys, mules and horses (with saddles, of course) in fences. *FOR ADDITIONAL INFO, REFER TO THE SCREENSHOTS BELOW. YOU MIGHT NEED TO ZOOM IN.*
4: The glitch will soon appear.

The only way to fix this is to reset your game.
Questions are welcome
