Swipe to go back much more difficult on TouchBar MBP

Project Member Reported by pinkerton@chromium.org, May 16 2017

Issue description

M59 stable, macOS 10.12.4

I've noticed that on my TouchBar MBP, swipe to go back is much more difficult. I have to swipe much longer and with more of an exaggerated gesture than with my 2yr old MBP. When it doesn't trigger, the "go back" arrow shows briefly at the left, but then I get the horizontal elastic overscroll bounce.

I wonder if it's because the trackpad is so much larger and we go by some % of travel, so a larger trackpad means a longer gesture (or more velocity) is required.

Is your gesture relatively quick or slow?
It's generally a quick, but with a short travel distance. I've found that extending the distance my fingers travel horizontally improves the chance of success, but I also add a little more velocity due to frustration.

taking out of triage queue. I don't have a device to test, but might eventually.

Code lives in https://cs.chromium.org/chrome_render_widget_host_view_mac_history_swiper.mm

git blame suggests erik might be familiar with it. Possibly there's a simple parameter tweak that can be made.

Well, I got that device :) #shiny

And the first thing I noticed was that my mouse felt a lot slower in general. I don't think I'd changed it on my old laptop, but bumping up the Tracking Speed in System Preferences seems to have gotten me back to a behaviour I'm familiar with.

But! I experimented and this doesn't impact the swipe gesture.

The swipe travel seems OK to me - maybe this is WAI. But personally, I hate that gesture since it confuses scrolling, and always disable it in preferences, so I'm not really a good judge :)
