By design:
This is by design. It's caused by baked GI relying on realtime GI and realtime GI marking some texels as invalid (normally done to avoid leaking when geometry intersects).

It will be fixed once we introduce our own progressive lightmapper.

1. Create new project.
2. Add package (in fb case).
3. Open scene Levels/Stadium_ARI_D/Stadium_ARI_D.scene
4. Check screenshot "crowdCardsBug.jpg", try to move camera to same position.
5. You should see same shadow and light artifacts.
