When viewing objects (including vehicles, characters, trees and buildings) through glass glazed windows (of buildings) the object may become invisible when viewed from a certain angle. If the object is moving it will appear to become visible and invisible multiple times as it passes through these angles. If the object is static, the player may move inside the building to alter the angle at which an object appears and disappears. This is particularly noticeable with the large glazed shop windows and particularly at the edges of the glass.
