This bug has been in Unity for a while. It seems to occur only at specific camera angles and when the spotlight’s angle value is high enough. Also, it only occurs in Forward Rendering.
It breaks the immersion and there doesn’t seem to be a workaround. If anyone could offer any help on getting around this issue, I’d be really grateful!
I’ve uploaded a package file that contains the required setup to see this bug in action. Just drag and drop the prefab to a scene.
