Repro:
1) Download project https://github.com/iM0ve/Automotive
2) Open CarDemo scene
3) Look at the columns
Result: Shadows are flickering and look incorrect. If you dont see the bug, try re-enabling Environment->Lights gameobject.
Im not sure if maybe my setup is incorrect or its simply a bug. I have tried using Cached and Realtime shadows, changing shadow atlas sizes but I still get the issue. Tested on srp/devs.
