Did a test with "Bloom" setting "Off" and the artefacts are still there for me, maybe there are some inverted normals or overlaps in the mesh. LE: They go away if I turn High Dynamic Range "Off" when having Reflections disabled.
Thanks, I tried the same and indeed, it's not the bloom. They also go away if I enable TAA or disable AO, so it must be a combination of the post effects and how they handle triangle or normal vector edge cases.
