One possible answer is that glass bends (refracts) light. This may no be too evident looking straight through a thin pain of glass. But looking through the glass near its edge provides a much longer path (and more refraction?). For example, the distance from the surface of a swimming pool directly to the bottom is less than from the surface at one end to the bottom at the other end. If light is diffracted (bent) its direction is changed and shadows depend on the direction the light is coming from.
