Dynamic objects flickering outdoors?

[TheRetroCarrot]

I've had an odd bug I've noticed recently, it's very minor, and isn't necessarily worth troubleshooting my 300+ mod load order. However I figured I'd check if anybody knew if this was a vanilla bug or engine limitation.

 

What's happening is that dynamic objects, such as wine bottles sitting around, firewood, etc, occasionally flicker yellow outdoors. It happens so quickly I can't actually tell if the texture is having issues, or if it's just that shadows are no longer casting on the object. I believe it's to do with shadows. Sorry if this is pretty vague.

Any ideas? Thank you.
