The problem with any drag/scroll is that the screen update both serves to show new content and how far you've navigated through the app / document.

The problem is that screen update usually cannot keep pace with the rate at which you can move through the interface, resulting in an unsatisfactory experience in both presenting content and revealing context.

Hard pagination solves both problems.

(Some displays can cycle between refresh modes offering a "fast" refresh during navigation, followed by a full blank and repaint on completion, though this may also require app support. I'm familiar with the Onyx BOOX configurations here, which offers a hybrid option for at least some apps. It's ... better but still not idea.)
