Due to this recent bug fix for MC-12729 made in snapshots 23w06a and 23w07a you can see extra cubes protruding towards the front and bottom of the legs of the humanoid entity models. This is most noticeable in humanoids with non-mirrored legs, including players.
Another thing to mention is that the fix also causes a gap between the legs of zombie villagers.

Changing it from being named "Protruding cubes" to"Different zfighting" would be factually incorrect. Z-fighting would be different planes that are so close together to the point where they fight to try and render above one another, this therefore causes an extremely screwed up effect where the two planes flicker during camera movement. there isn't that particular issue here anymore as the planes are no longer fighting to render over each other. This instead is a whole new bug/issue caused by the MC-12729 bug fix in 23w06a which was intended to fix leggings and boots. This would indicate that all the humanoid entities (including the armor) all share the same model, this means that solving this bug as a duplicate of MC-182699
(which was already fixed as a result of the models being shared) is a pretty questionable decision.
I do not expect you guys to know how deeply intertwined all of these bugs can be sometimes. I do, however, expect you guys to understand that this would be a new bug for a new issue based on what I've just further explained in this comment.

Yeah, this is not a duplicate, it's rather that the legs still intersect, but at slight yaw rotation. There's no z-fighting here, only intersection.
