There was a bug that was allowing people to aim at a room, with a weapon or with cyberware, and then look through the exits in that room. Basically, imagine you were on a rooftop. You aim at the room to the north, below you. You then could 'look south' and see into the building you were in.
There were some use cases where this was viable. If you were aiming from a street with telescopic lenses and you looked in the same line of sight. This gave people the misperception that this was not a bug. However, generally, this was broken. It's been fixed. No more looking through exits while aiming.
