Emissive textures Z-fighting
I am also having the same issue, and with some testing I've found the z-fighting seems to occur on certain corners. The behaviour occurs on multiple packs with emissive textures.
A flat 5x5 plane:
The same plane with a block placed in the center (z-fighting highlighted):
+1
I thought I was going insane and it was there the whole time. Seems its new!
The issue is worse now, and different faces are affected. Up to three faces per corner can be affected.
It also interacts with light levels strangely (non-fighting blocks removed for clarity)
The issue may be worsened by Sodium's compact vertex format. Regardless, it cannot really be fixed.
As a workaround, is possible to fix manually by removing pixels from the base texture that appear in the emissive texture, but this will cause those textures to look completely incorrect if emissive textures are disabled.
I just tried turning off smooth lighting and all Z-fighting stopped (including corner fighting), is that related to the vertex format?
Smooth Lighting is the weird cause of this, It seems. Turning it off makes it work fine, But the rest of the lighting then looks worse.

adding to this for anyone doing such; blocks that naturally give off light seem to be unaffected (enchanting tables, crying obsidian, etc) it's strictly non-light blocks that cause the z-fighting, which helps to slightly reduce the load for editing bigger emissive packs
this can be best seen with redstone ore; when unlit z-fighting is present, though when lit it's as expected (no z-fighting)
Until this situation gets resolved, 3D ore packs using emissives may be unuseable.
I found a way to keep the emissives without the 3d textures.

Is it possible to not render those pixels that are covered with emissive texture? AND to do it only when emissive textures are enabled.
This issue used to not exist. It seems a sudden affliction.
if i had to guess the recent sodium (& related (indium, iris)) updates caused it since downgrading back to previous versions leads to it being normal again
which isn't surprising given the sodium update broke a lot of mods, even some that you wouldn't expect like mod menu at least with what i've run into
Hoping this gets fixed. . .
Im still having issues, And dont feel like having to use shaders constantly for ores. For now I'll just use Reimagined, But F for my FPS.
Do we have any ideas as to what is causing the issue?
It appears to be related to smooth shading as the z-fighting stops when you disable it
Hopefully this can get a resolve. This is getting more annoying each time I have to deal with it. Sadge. . .

This bug has been bugging me for quite some time. Any new information on this bug?
MoreMcmeta seems to have fixed this same issue in their emissive plugin. Might be worth checking how they worked around the issue. https://github.com/MoreMcmeta/emissive-plugin/issues/10
I tried patching it by just removing the textures under the emissive layer manually and, uh... that didn't work lol
I hope to see an eventual real fix to this bug!
