Slow Scrolling

I’m new to Scrivener, but in both a new project that I’ve created and in the tutorial project I’m running into issues with scrolling behavior not matching that on other MacOS programs. I do all of my scrolling through two-finger scroll on a touchpad or lately one-finger scroll on the Magic Mouse. Applications are incredibly consistent and predictable in the number of page-inches scrolled for each finger-inch (at a given speed) on the mouse; that’s part of what makes that kind of scrolling easy to use.

With Scrivener, however, I’m finding that the distance scrolled is varying with the height of the window. To reproduce: I opened a new tutorial project. When the screen is sized so that 40% of the “Start Here” document is displayed scrolling is very consistent between Scrivener and any other apps. If I then grow the window so that 90% of the document is displayed, scrolling up or down becomes very sluggish - to the point that the same finger-movement needed to go from the top to the bottom of the small window is needed to move the document about 1 screen-inch.

When the document is sized so that 90% of the binder view is shown, the two panes behave differently; the binder scrolls as expected while the text scrolls much more slowly.

This represents in other situations/documents too, that’s just the easiest way I can find to reliably reproduce it. This is on version 2.8.1 (build 26322).

FWIW this is constant using my 2012 MacBook Pro with a touchpad or my brand new 2017 27" iMac, so it doesn’t appear to be system-related or indicate a lack of system performance in general. The most recent thread I found on this was from 2015 so I figured a new post was appropriate.

Thanks for any assistance; looking forward to getting a lot of use out of this product!
