X Input 2.1 Smooth / High Resolution Scrolling Now Supported By Chrome

With the latest Chrome/Chromium browser builds from Google, X Input 2.1 smooth scrolling / high-resolution scrolling is now supported. This should make for a more responsive and smoother scrolling experience atop recent versions of the X.Org Server.

A Phoronix reader pointed out that the X Input 2 scrolling improvements are finally in Chrome with M54 (released recently) after the bug report for supporting this functionality was opened back in 2014 and the X Input 2.1 changes have been present since X.Org Server 1.12. This smooth scrolling in Xi2 aims for pixel-precision.

The code has been in Chromium since the beginning of the year but the X Input 2 support was disabled until M54 due to open bugs.

Firefox has also been working on the X Input 2.1 smooth scrolling support per this bug report but it will only be working for the GTK3 version of the browser.
