I have run into this new display artifact behavior in Unreal 5.0.3 where I can see triangles flickering if my view is at certain angles.
Here is a vid of the artifact triangles.
Any ideas on how to address this problem? Thanks 
Ok, I figured it out…
The setting r.Shadow.Virtual.ContactShadowLength was set to 0.02 which I think is ok in some scenes. When I set mine to 0.05 the flickering reduced to farther away. 0.06 seemed to remove it completely.
–edit-- though I keep having to set this each time I start. How do I set this value permanently so I don’t have to keep setting it how it works in my scene after restart?
