More or less the same category, so I'll jump on your train.

Attached some screenshots made in khelm during sunrise.
Same room in both pics, sun is shining from the doorside of the room.

Sun shines through interior walls and doors, reflecting on the floor and the opposite walls.

Not that big kind of bug like torches shining through walls, but maybe related.

Edit: In my case, theres was no change in illumination while moving.

Related to #0000584
