Consider this.

In the Church scene of FF7, she was seen to be sitting next to two childs prior to her flashing process; disappearing out of no where.

In the end of AC, she was definitely a ghost and was also seen to be sitting next to two childs before flying away with Zack in flash light.

See the connection? So, it can`t be a glitch, not fully, anyway. Maybe Square have forgotten to disable the flashing process BEFORE her actual death. It would be nice if they actually wanted this to happen, it sort of gives you a 'premonition' feeling.

Remember that FF7 was the first 3d game that SquareSoft has created, so it would be reasonable to say that they didn`t know much about 3d modeling at that time. For example, if they had better knowledge in the field, they would have made the model of Aeris transparented, instead of making it flashing. As far as I`m concerned, there`s no such thing as transparented model in the game.

Maybe you exaggerated about the 'many, many glitches' part a bit, but either way, the game actually doesn`t have that many glitches, let alone the related ones to the story.
