I'm not familiar with EFL, but this almost sounds like event delivery issues (eg. both the UI and WebCore try to apply the scroll delta and this conflicts).
Does EFL use delegated scrolling or does WebCore handle scroll events?
Or an incorrectly updated visible rect could also be a source of the issue.
