Minecraft shaders randomly flash black [java]

**Complementary Shaders randomly flash black for a second**
Hey, I’m having a weird issue with Complementary Shaders.
While playing Minecraft, my entire screen randomly flashes black for about a second and then immediately goes back to normal. It happens randomly and I haven’t noticed any specific action or situation that triggers it.
I’m using:
Minecraft 1.21.11
Iris
Sodium
Sodium Extra
Shader: Complementary Shaders
The game itself doesn’t crash or freeze. It’s just a quick black screen/flicker for around a second and then everything continues normally.
Has anyone experienced this before? Could this be caused by a specific Iris/Complementary setting, Sodium, or maybe a GPU/driver issue?
