About this image

This 'whiteout' occured to me when i entered some ruin (i.e. where exusing ghosts are - posting in hurry, cant remember the name. ill add later;) ), i think its related with ghosts becasuse they (those exusing ones) randomly change image to a common npc/living human when i fight them... full change - till death or only half of a body is ghostly, it changes after hits...

The first time ive encountered this was in the ruins with Raghun Dragon Priest Mask quest(or different, proper name).

Now, ive discovered that shout + ethereal state, when used and used off, repairs this overall whiteout. But ...well, its strange.

Im using many mods like: skyre, enchanced light & FX with realistic lightening overhaul and climates of tamriel, skyrim momod v12, skyrim 2K textures and almost all enchancing graphic mods suggested by the author of RealVision ENB - but without this awsome ENB, just casual mods.
On previous saves i have no such problems and ive changed really nothing...

Anyone's fammiliar with this?
