Glow instead of shadows

How it is possible?
Glow instead of shadows behind a door

couple of doors like this, the others doors is normal

I’m guessing there’s enough of a gap between the door and the door frame that light is coming in that way, or some other direction

It’s more like a Lightmass Glitch. Try to change the lightmass quality / options to see if it’s the same ?

Yep!
But if to make a door not parallel to a wall - everything is all right
