Screen Flashing with mupen64plus and rice plugin

Hello, I was playing the game F1 World Grand Prix II, but there is a constant "flashing" were parts of the screen momentarily becomes white, giving this "flashing" appearance. I searched the internet and found several links saying to change the "ScreenUpdateSetting" that I found in the "RiceVideo.cfg" file. I tried several settings (0,1,2,7) and the problem persisted. So what can I do to try to solve the issue? Mupen version is 1.5, as is Rice plugin.

Thanks for the answers.
