If you aren't experiencing any actual graphical issues, OpenGL errors are unfortunately kind of normal with OptiFine. I may be slightly off on the exact wording, but you can turn off the error messages under:

Settings > Video Settings > Other > Show OpenGL errors.

If you are experiencing issues beyond the error text, post your full log somewhere?

  • Have you tried updating to the latest version of Complementary Shaders? It looks like we're at 4.2.2 now.

I would recommend two things to solve this issue:

  1. Update ComplementaryShaders to the latest version (v4.2.2)
  2. If the issue still persists, attempt using Iris Shaders instead of OptiFine (This was mentioned in the ComplementaryShaders Project Page)
  • This is good, but I want to control shader settings without mod

  • Could you specify what you mean by that? You need to use either OptiFine or Iris to load ComplementaryShaders, as stated by their Project Page. Nov 6, 2021 at 6:47
  • This option image Iris Shaders doesn't have this button
