A quick bump to this thread with some additional info I've gathered.
This seems to be related to most/all light sources that are bright white/blue-ish.
The most common places are the Necralisk and the new tile set. But I've noticed issues during the "cunning drift" puzzle fight as well. And the small yellow drones that the corpus can summon... their light can be seen through walls on occasion now.
My guess is that this specific light effect got moved up on the priority list somehow, thus no longer taking into consideration that it should be behind things and thus occluded or even just diffused.
