Wonder Square graphical glitch - White Squares

[GilgameshGG]

I just got to Gold Saucer for the first time in disc 1, and I went to check out the Wonder Square.. and this is what I see:

Basically, there's an overlay of white squares trailing in diagonal directions over the actual screen. You can tell, because Cloud's arm is being hidden by it. The only thing that pops up over it, is the Battle Simulator mini-game's fighter models (as seen in the pics)

It's not buggy or crashy or anything, but it's a bit.. distracting and immersion-breaking. It's the only place so far where I've had a graphical bug.

Has anyone had this glitch before?

Anyways, here's my 7th Heaven mod loader log file.
I tried deactivating 'Wonder Square' in the Minigames Collection, but it didn't change anything.
