            Bug ID: 188471
           Summary: Tons of rendering artifacts with AC enabled in
                    https://lichess.org
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Critical
          Priority: P2
         Component: WebKit Gtk
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: svillar at igalia.com
                CC: bugs-noreply at webkitgtk.org

Steps to reproduce:

1- Goto https://lichess.org
2- Move the pointer around, hovering the various UI widgets in the page, also click on some menu (even start a game if you fancy)

Expected outcome:
Good rendering

Actual outcome:
Tons of rendering artifacts, a lot of stuff drawn on places where they should not be

Looked like the typical issue with AC, so I tried WEBKIT_DISABLE_COMPOSITING_MODE=1 and then everything works fine.
