Expected Behavior

Chunks that are visible underwater or visible while blind are not culled, since they are visible.

Actual Behavior

Chunks far enough away are culled, causing it to look strange underwater compared to with that option disabled.

Reproduction Steps

1. Turn Fog Occlusion on
2. Go underwater and observe. Chunks far from the player are not rendered.
3. Turn Fog Occlusion off
4. Observe again. Chunks are rendered properly.

Attachments

From my observation, it does render in after a while. It seems to be culling due the fog distance being changed when underwater.

Probably because of this.
