UE5.1 Lumen reflection noisy shadow issue


I am having issues with lumen reflections. There are a lot dark noisy spots in the reflection. Anyone have any inputs on how to improve it?

Many thanks!

Yeah I have the same problem in 5.3. It seems like mirror reflections are showint Lumen Scene view mode instead of Lit mode… I don’t know why and don’t know how to fix it. I assume that other reflections on non-mirror materials are flickering too?
