Lighting flashes when swimming on the surface after swimming underwater
Seems like the lighting might be based on somewhere a little below where the camera actually is located.

What I expected to happen was...:
Lighting to be like when you are on the ground when swimming on the surface

What actually happened was...:
The lighting flashes as you bob up and down while swimming on the surface, happens for both sprint swimming and normal swimming

Steps to Reproduce:
1. Swim underwater for long enough to have a noticeable difference in water vision to make it easier to see
2. Without leaving the water, swim along the surface
3. Observe world lighting flashing between normal and water vision
