            Bug ID: 210636
           Summary: webkitgtk-2.28.0 causes epiphany to abort
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK
          Assignee: webkit-unassigned at lists.webkit.org

https://gitlab.freedesktop.org/cairo/cairo/-/issues/400

Using epiphany-3.36.1, webkitgtk-2.28.0, cairo-1.16.0, gtk+-3.24.18 compiled both 32-bit and 64-bit.

When clicking on a youtube video, epiphany aborts with:

epiphany: cairo-surface.c:1733: cairo_surface_mark_dirty_rectangle: Assertion `! _cairo_surface_has_snapshots (surface)' failed.

The suggested fix is:

I would expect that this problem goes away when adding cairo_surface_flush(m_surface.get()); at line 203 in https://github.com/WebKit/webkit/blob/ed000b08b8305908a4802b1889578e68f4c18e9b/Source/WebKit/UIProcess/gtk/AcceleratedBackingStoreX11.cpp#L194-L196
