Using gnome-web, visit tweetdeck.twitter.com, make a web app out of it, and log into it with your Twitter account. Add a bunch of columns (I have 15 of them) so that there is horizontal scrollability, and then scroll horizontally (ex: using two-finger horizontal scrolling on a touchpad, or shift-scroll).

Result: jerky/janky/sluggish scrolling, whether you are on Intel graphics or open source radeon graphics.

Tested on GNOME's Xorg session on Fedora 33.

In comparison, Firefox is butter-smooth for the same usecase.

Can this be reproduced in Gnome Web 44.2/ WebKitGTK 2.40.1? I don't have Tweetdeck so can't test.

Still happens with version 44.2 and WebKitGTK 2.40.1. It might be a bit less noticeable for me now on Wayland with triple buffering, but still noticeably less smooth, and a bit more jumpy, than Firefox.
