Third person deactivates shaders

When I was using shaders(Super Secret Settings), whenever I went into third-person, the shaders deactivated.

What I expected to happen was:
Go into third-person with shaders.

What actually happened was:
I went into third-person, but shaders deactivated.

Steps to reproduce:
1.Click "Super Secret Settings"
2. Go into third-person(f5)
