Sorry for the vagueness, but I really don't know a better way to describe the effect. It generally happens in every ps1 game I emulate, but I really don't pay attention to it. However, dealing with the issue would be nice.
If there's a thread that I'm apparently not aware of already highlighting what I'm talking about, please point me to it!
