Using anything other than TemporalAA causes artifacts

With TemporalAA turned on in Engine - Rending:…53a3200f03.mp4

With TemporalAA turned off or using any other AA:…9ad07f7d97.mp4

Anyone know how to fix this?


I turned off Screen Space Reflections in post processing options and it fixed the problem but now I don’t have any screen space reflections.

Edit 2:

Found someone else with the same problem Unreal Engine Issues and Bug Tracker (UE-93360)
