Sheep graphics are glitchy.

I was a little too soon with posting this, just realised it happens with pigs too, so probably with every mob

Atleast yours is only exclusive to Sheep. My game suffers from the same bug but instead of sheep, all of the entities (mobs, chests, signs, armor stands, paintings, item frames, piston heads, dropped blocks, etc.) appear to be glitchy. One of the Pros is me having an Entity X-ray (I can see if there's a mob behind a corner, i can see if there's a trap involving pistons, and i can see if someone drops an item behind a wall). Cons are it only works for entities behind 1 block thick walls, "X-ray" only works at a certain range, I can't read signs properly, Taking photos of builds with entities ruin it (I wanted to show my friends my house but unfortunately my storage pile was blocking my view of the house).
