Hi
I have been struggling with flickering mesh with lumen real-time rendering and recently I found a solution to the issue that I want to share if anyone else has the same problem 
With most of the thin meshes in my scene, the real-time render flickers, and can’t settle on a stable image to render. So in the documentation under Temporal Super Resolution, which is the Anti Allising Method I’m using, I found the section Adjusting for Pixel Flickering.
Here it says you can use this console command, to decrease the flickering:
r.TSR.ShadingRejection.Flickering.Period
For my scene, I had to set it to 100 for it to remove the flickering altogether, but it seems to not have a noticeable performance impact. There might be other reasons to not set it that high but this works for me.
Here is the link to the documentation:
