1851258 - Consider changing default kinetic scroll mode from page scrolling to pixel scrolling on the release channel

Status: RESOLVED FIXED

(Core :: Widget: Gtk, enhancement, P3)

Description

[Botond Ballo [:botond]]

Filing this as a follow-up to bug 1753033, where we changed the default kinetic scroll mode (apz.gtk.pangesture.delta_mode) from "page mode" to "pixel mode" on the Nightly channel.

This bug tracks the potential rollout of that change to the Release channel.

I'm filing it mostly so that I can hang off of it the various regressions from bug 1753033 that have been noticed by Nightly users, which we should address before any such rollout.

Has there been any progress?

Setting apz.gtk.pangesture.delta_mode = 2 (maybe with apz.gtk.pangesture.pixel_delta_mode_multiplier = 25) works as intended and should IMHO be the default on new installs as this matches what (new) users expect and ~ the scroll behaviour of other native GNOME/libadwaita gtk apps.

Are there still any blocking bugs besides bug 1849201?

It's been enabled for a long time on Nightly without issues. There's an
underlying APZ issue here tho (that's tracked in bug 1944697), but no
reason not to do this IMO.
