Light bug in ocean and underground

[ujckap]

Describe the bug

Light bug in ocean and underground - Incompatibility with Sodium?
(I haven't seen it anywhere else, for example in a plains biome)

If I reload chunks, the bug disappears.

The problem occurs when I use C2ME + Sodium. If I use only C2ME or Sodium - there is no problem, same when playing without mods.

I also saw this in 1.21.1, 1.21.5 and 1.21.8 all mods were updated to the latest version

To Reproduce
Steps to reproduce the behavior:

1. Create new world or join existing world
2. Fly over the ocean

Expected behavior
I expect that there will be no buggy light

Looks like CaffeineMC/sodium#3218

Does this fix itself when htting F3+A?

[ujckap]

Yes

[ishland]

Please try running a dedicated server with only c2me, plus the client with only sodium, and see if it still happens.

It still happens
