I've started FFIV again on my PS3 and there has been some odd glitches in the game. Any environment pieces like columns, dressers, have black flashes emanating from them. Also things like water or gaps in dungeons flash as well. Sometimes when I'm entering an area the game's music skips for a bit. Is there something wrong with my disc? I checked it for scratches and it seems to have no more than was there when I was playing it on my PS2.
