I don't know ¯\_(ツ)_/¯
I just turned it off in my game
Lumen is a very performance heavy tech and works best on high end machines. It really likes ray tracing. And my laptop can't generate Distance Fields properly, so it creates a very bad ghosting effect. There was a similar effect in your game, so I suspect they weren't generated in your game either, but I don't know if it's my laptop's or your machine's problem.
