There are several position related glitches, when far away from origin (0, 0).
These include particles rendered in wrong locations (at least torch flames and the new particles from hitting the ground), sounds playing from incorrect directions, and even glitched cactus hitboxes.

Steps to reproduce: teleport to near the world border, say x = z = 29 999 900. Place some torches: the flames are rendered even almost 2 blocks away from the correct position. Fly up and drop down, the particles are rendered about 0.5 - 1 blocks in the wrong location. Punch some blocks, move around a bit, and the sound seems to jump around and come from weird directions. Find or place a cactus, and it has a strange long and narrow collision box.
