Pigs are having a texture issue, they seem to be brown with some parts of the face missing. It has a small area on the front chest near the neck with maybe 3 textures of chests. The chest overlaps themselves and the one that is visible has the locking part of the chest. It still has 2 eyes, but one is on the side with only the black pupil on the front of the face. the second eye (the same as the first) but near the back of the head. The pigs still function as intended, though spectral arrows don't show the blank spots where the pig would normally be. I also revisited pigs on my device with pocket edition, I'm also not using any mods, code, texture packs, or shaders, though I just got Java edition the day before. ( I can't get the screen shots I took to work for this bug report, but I might try another report with the screen shots)
Please provide some screenshots or videos of this issue occurring, whilst the F3 Debug screen is enabled.
