            Bug ID: 245783
           Summary: [META] Slow performance issues tracker bug (scrolling,
                    animations, drag & drop)
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK
          Assignee: webkit-unassigned at lists.webkit.org

                CC: bugs-noreply at webkitgtk.org

Here's a meta/tracker bug related to all the performance issues I've found to be debilitating for real world usage of Epiphany. I am typically testing with open source Radeon graphics on my desktop computer (AMD Radeon R9 270 GPU, 8-cores Intel Xeon CPU) and on my ThinkPad X220 (Intel Sandybridge CPU and graphics). Issues occur both on X11/Xorg and in a Wayland GNOME session.

Most of the issues are what Mozilla calls "jankiness", i.e. visible lagginess when scrolling in particular, though some may be experienced with animations or drag & drop interactions. Combined, they make the browser unusable for me, for anything except occasional testing out of curiosity. Firefox and Chromium are butter-smooth in comparison.
