            Bug ID: 220085
           Summary: Scrolling is slow / janky on Tweetdeck (Twitter) with
                    Epiphany web apps
           Product: WebKit
           Version: Other
          Hardware: Unspecified
               URL: https://tweetdeck.twitter.com
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK
          Assignee: webkit-unassigned at lists.webkit.org

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.
