Autoexposed problem

[MoTao233]

Autoexposed seems to have serious issues.
After entering caves, there are lots of noise, and the exposure is abnormal.

The version I'm using is 1.20.4, and I encounter such problems whether on Optifine or Iris.
I really like the style of this shader. Could you spend some time fixing it? Thank you !!!
