Oh. Strange. It was good from the beginning. Then I open spellbook for first time, found strange fire spells, ALT+TAB, report it, return, close book... oops, everything goes blurry.
Cloth map still good, though. 
Oh, wait, there is more! 
When everything goes blur, models stays good. I could check my Sovereign with full details.
But when I disable Lightning, everything go in place... except cards/3D models.
Now they are blurring!
