The Bug:
Z-fighting can be seen at some distances when fire is present on the sides of blocks.
Steps to Reproduce:
Summon a wall of burnable blocks that are on fire by using the commands provided below.
/fill ~1 ~1 ~1 ~15 ~9 ~1 minecraft:mangrove_log
/fill ~1 ~1 ~ ~15 ~9 ~ minecraft:fire[south=true]
Stand a fair distance away from the wall and look closely at it.
Take note as to whether or not z-fighting can be seen at some distances when fire is present on the sides of blocks.
Observed Behavior:
Z-fighting is present.
Expected Behavior:
No z-fighting would occur.
I was able to reproduce this in a creative world. I'm unsure because it is kind of hard to tell exactly when, but it seems to start around 20 blocks away. It also seems to only be happening with minecraft:mangrove_log.
