If neither of these solutions work for you, or if you find another solution that does work, please contact us at support.
The newest versions of Riptide GP2 and Beach Buggy Racing and Shine Runner all have the screen scaling issue fixed and are now released. You don't need to do anything, just update to the latest version and it will work.
