[Issue]: Glitching sun/moon at sunrise on BSL shaders

[Creeper-banner]

Description

When using BSL, there are black areas around sun and moon at sunrise time.

Step to reproduce:

1. Create / enter a world
2. Set the time to sunrise (e.g. /time set 23000)
3. Then the visual glitch appears.

However when I switched to an Intel iGPU then the glitch disappeared, so it might be hard to fix this...
This seems to happen on every versions of BSL since v8.2.05.

Mods:
Unimixins 0.1.23
FalsePatternLib 1.10.3
SwanSong 1.2.6

System info:
OS: Windows 11 25H2 x64
CPU: Intel Core i7-14650HX
GPU: NVIDIA GeForce RTX 5060 Laptop GPU
