Called under fairly specific conditions (NOT ALWAYS), but can occur during gameplay. If an antimatter explosion occurs when there are currently 0 mobs rendering, at a certain angle (~-arctan(√2)), the explosion will be distorted, it will become almost transparent (and sometimes invisible) and its color will change to yellow (sort of)

EDIT 3: absolute, 100% way to reproduce:

1. create a super flat world
2. /gamerule doMobSpawning false
3. difficulty - peaceful
4. /tp distant coordinates, 15000 or something like that
5. take an antimatter cell and throw it at an angle close to -arctan(√2) (-54.7356°)

video detailing the process:

EDIT 4: Here is the world to reproduce, all you have to do is drop the antimatter cluster and you will see the error (I recommend making the fov bigger)

I don't know if it's been pached bu the tau cannon don't render the shot if you look down
