This behavior was introduced in 25w31a.
Steps to reproduce
Join a world with commands enabled.
Summon multiple breezes. For convenience, it is recommended to enable the
NoAI
tag.summon minecraft:breeze ~ ~ ~ {NoAI:1}
Position the camera in a way that the breezes are lined behind each other.
Optionally, freeze the game’s ticking to halt the wind animation and make the issue more noticeable.
tick freeze
Observe the translucent parts of the breezes for a short while.
Observed behavior
The translucent parts will flicker, with their rendering order intermittently being incorrect.
Expected behavior
The translucent parts would be ordered correctly at all times, as was the case in previous versions and still is the case for the non-translucent parts.
thats not zfighting, thats improper translucency sorting
