Minecraft wiki entry for Historical_effects, associated text: The corner of the world in Beta 1.5, with the void particles clearly losing precision.
The corner of the world in Beta 1.8 Pre-release, with the grid pattern of particles clearly visible.
The void in 1.6.2 from within.
Void particles near the end of their lifetime in Beta 1.8's development, still not precisely generated.
20 blocks short of the 30 million mark. Not only are the torches and their flames not lined up, but the flames each picked a different direction to bend.
Void particles in the world boundary appear in very specific patterns.
Particles are in wrong position.
A redstone torch hanging on solid boundary air in Release 1.7. There is a noticeable particle position desync.
Torches placed on glowstone next to the invisible wall, the particles emitted from them are also in the wrong place.
Redstone ore lit beyond 224 on all three axes in 1.12.2 (as seen via the Cubic Chunks mod)
Four blocks of redstone ore lit beyond 225 blocks on both axes
A command-summoned TNT's explosion at 1,500,000,000 on both X and Z axis. The white and black smoke particles spawn in two different locations and different from the location of the TNT, due to floating-point precision errors.
