Conquest of the Horde

Basically every time I go invisible or use the invisibility potion, my screen gets soo messed up that I can't see anything.

What are you talking about? Isn't that how it's meant to look?

Sounds like your video card is taking a dump...

It dies especially because when you use invisibility potions the WORLD changes. I'd guess driver updates or a new chipset would fix this.
