Is there an existing issue for this?

Current Behavior

The scroll is junky, scrolling large chunks of the page instead of smooth from default browser

same problem, jumps by 500 pieces with one mouse scroll

Yep, it probably should be something configurable. I can add it as a new parameter in InAppWebViewSettings 👍.
By the way, what could be the best default value for it? 1 should be ok?

yes I think 1 is the best solution, because everyone expects the same behavior as in the browser

Released new version 6.2.0-beta.1. The default value is 1 and you can change it using InAppWebViewSettings.scrollMultiplier.
