Shadows not disappearing

While I was working on something on my alt on build mode with the F3X tools I moved my build then noticed this bug, I waited for a while to make sure its not lag but its still there…

I’ve seen this before; I don’t have any solid repro for it, but fortunately, it goes away eventually.

I too am getting this now, and a lot of it. It seems to happen with models instead of parts for me

I’m having different shadow problems - when I turn the camera in a certain environment (completely random and hard to repro) some lights flicker on and off.
