I never heard of such an issue, but if we want to solve the problem, we will need to have some extra info. Some questions I can think of:
- What do you mean by scrolling? Is it in the loader, or in the game itself?
- Which version of USB Loader GX are you using?
- Does the problem occur when using another loader?
- Which games seem to have this problem?
- Which cIOS are you using? Does using another cIOS solve the problem?
- What is your current configuration (syscheck)?
