Graphics issues with some games Mupen64Plus

My build has been running perfectly but i’m having problems running games like Road rash 3D the screen cuts off half way. however i’m not having this problem with California speed or other games in fact some of them will have the screen go black idk why it does this. what should i do to fix it?

the games do run full speed though even without my shaders on.
