Hello,

as there is the ability to modify the beam of the End Crystal, this has opened up the possibilty for some visual glitches:

Depending on how far you set the beam out, more visual glitches occur, here are some examples:

First visual glitch after a million blocks

As you continue to set the trail further out, it becomes even more glitched

Going out further and further, the trail glitches up and down, depending on where the End Crystal currently is

The trail becomes more pixalated, until it eventually disappears.

Please note, that this behavior is really weird, as it dosen't disappear always at the same time. It might disappear over 100 million blocks out or might just disappear way before hitting this milestone.

Although this bug is not visible within the vannila bounds of the game, Mojang has proven to fix some odd bugs way outside of vanilla bounds or survival capabilities.

To reproduce this issue, run the following command:

/summon minecraft:end_crystal ~ ~ ~ {BeamTarget:{X:50000,Y:0,Z:0}}
