Additionally, if leaves are covered by snow, the extra leaves also turn black

What other mods are you using? I wasn't able to reproduce this. This seems to me not z-fighting related, but rather that the extra leaves from the blocks behind the visible ones are not getting light which makes them render in pitch black.

What other mods are you using? I wasn't able to reproduce this. This seems to me not z-fighting related, but rather that the extra leaves from the blocks behind the visible ones are not getting light which makes them render in pitch black.

I must have misread it; it should be unrelated to z-fighting. Here's my mod list:

[Kynake]

This also happens with Twilight Forest's Dark Leaves, as noted in this issue.

[Kynake]

I've made a PR with an attempt at fixing this (or at least reduce it a bit). @Omgise Are you able to test it?
