1. Set view distance (or terrain/map draw distance) to 25,000 meters.
2. Set weather to overcast.
3. Ascend high into the air (e.g., via flying vehicle or camera).
4. Observe the cloud shadow boundary — at long range, shadows disappear and reappear in a loop near the draw distance limit.

Expected Result:
Cloud shadows should extend smoothly across the entire visible area up to the configured draw distance, with no visible popping or cycling.

Actual Result:
A shadow rendering boundary appears where shadows fade out, then fade back in repeatedly, breaking immersion.
