Distant buildings textures flickering black

[Decèdere]

So far I've only seen this on Whiterun and the windmills around it.

 

I only have these mods affecting graphics. I installed them with Vortex and I have no idea what order they should be in. I installed A Noble Skyrim last because I noticed blurry textures on buildings outside Whiterun.

 

SMIM

Enhanced Lights & FX

A Noble Skyrim

Ruins Clutter Improved

SkyFalls & SkyMills

 

I also noticed sometimes I see shadows pop in and out depending on where I look. I assume it's an ELFX thing. Is that a known bug or should it not be happening? It's very rare that it happens.
