Not the case of WPE. Not at least using a build from trunk. 1857152 6 johnfactotum1 2022-03-31 21:55:17 -0700 Tested on Arch Linux, with webkit2gtk-4.1 and webkit2gtk-5.0 2.36.0. Kinetic scrolling seems to be working with GTK 4. But overflow scrolling with PgUp/PgDn still has no animation. On GTK 3, overflow scrolling is neither kinetic nor animated. 1857228 7 alicem 2022-04-01 04:35:48 -0700 Huh. Didn't think it would depend on GTK3/4. I see they are using different codepaths when creating a NativeWebWheelEvent though, I guess it has to do with that then. 1893678 8 psaavedra 2022-08-25 04:42:38 -0700 Update: Works on Ubuntu for WebkitGTK (libwebkit2gtk-4.0-37:amd64 2.36.6-0ubuntu0.22.04.1) 1893689 9 psaavedra 2022-08-25 07:18:16 -0700 Update: * Works on Ubuntu for WebkitGTK (libwebkit2gtk-4.0-37:amd64 2.36.6-0ubuntu0.22.04.1) * But not kinetic at all in overflow elements for (libwpewebkit-1.0-3:amd64 2.36.0-2ubuntu3) 1894511 10 psaavedra 2022-08-29 06:51:36 -0700 Pull request: https://github.com/WebKit/WebKit/pull/3770 1895781 11 ews-feeder 2022-09-02 07:47:14 -0700 Committed 254099@main (431d9f7c6bc7): <https://commits.webkit.org/254099@main> Reviewed commits have been landed.
