So me and a friend bought FFIV:AAR on launch and got everything set up.

My friend however is having serious issues.

I don't really know how to explain it other than the screen flashes different colors quickly while walking or talking. Or anything.

It would be fine and then a line of red flashes quickly on the screen and goes away. I've searched everywhere for the problem and she has reinstalled the game up to three times so far. Does anyone else have any suggestions or at least confirm that they have a similar issue? Any other game seems to work just fine.
