I'll move this to help & support until confirmed this is actually a bug and not an issue with mods, installation, hardware, etc.

Very good. This specific subforum is geared toward an unmodded DFU, so you'll want to post in the dedicated topic for those mods.

Handpainted models
Real Grass

Try adjusting the real grass setings, change the Grass shader to "mesh"..

Unfortunatelly I cant help more, Ive never encountered this bug, your system seems ok.
I use cca the same mods as you are, just windows 7

I have heard that distant terrain + mountains and hills can cause issues together, try diabling one of them. I've also personally had some issues with vibrant wind, so you might want to try diabling that too.

I know I should've, sorry. Unfortunately that was on an old PC that I don't have anymore.

Hi.
I was experiencing the same issues as shown in OP's screenshot. Both exterior and interior light sources are affected. When lights cast by these sources are viewed from certain angles they look as they should, but when the camera is rotated the lights will not be rendered at all. The blocky artifacts appear with certain mods enabled, but those are only a secondary problem. The problem persists with no mods enabled. Using the alpha 0.10.4 for windows x64.

If you are experiencing this problem, try disabling USE LEGACY DEFERRED RENDERING PATH in the advanced video options.

Unfortunately it seems that the realtime reflections mod requires this setting to be turned on.
