FF7 and FF8 have community made graphic subsystem replacements that are a mixed bag in this regard.
I've personally had good experiences with the opengl renderer, but not everyone does.

I dont think this is the latest version of the driver in question. I have fuzzy memories of it becoming a github hosted project with newer releases.
Back up your current install before mucking about.
The issue in question comes from lack of palletized texture support from your video hardware/driver, and the game not having a good way to deal with that. The community made renderer handles this 'acceptably', imo. Again, not everyone agrees.
