What I expected to happen was...:

Changing from "Fast" or "Fancy" to "Off" should disable cloud rendering and remove existing rendered clouds.

What actually happened was...:

Clouds remained as artefacts on the screen - locked to POV and not their original location in the sky. Cloud artefacts persist between multiplayer server connections - only disappearing after restarting the game.

Steps to Reproduce:

1. **Look at the blocky blue sky with clouds enabled
2. Disable clouds
3. Clouds are still there
