            Bug ID: 164983
           Summary: [GTK] Slow copy and paste between workspaces
    Classification: Unclassified
           Product: WebKit
           Version: Other
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Gtk
          Assignee: webkit-unassigned at lists.webkit.org

Copy and paste between applications where either the source or the destination application has a WebkitGTK+ widget can be slow.

Environment: Gnome Shell on Wayland
Version: 2.14.1-2.fc25 (Fedora 25)

Copy and Paste will fail when the applications are on separate workspaces.  When the applications are on the same workspace copy and paste works fine.

Copying *from* a WebkitGTK+ application to a any other application requires the source application to be visible after "paste" is actioned.  This requires swapping backwards and forwards between workspaces.

1. Start a WebkitGTK+ application (epiphany) on workspace 1.
2. Start a different application (gedit) on workspace 2.
3. Go to workspace 1, and select text, context-menu -> copy.
4. Go to workspace 2, context-menu -> paste
   ... nothing happens.
5. Go back to workspace 1 (do nothing)
   ... text has been pasted
6. Go to workspace 2, confirm pasted text.

Various applications were tested.  The two WebkitGTK+ applications that were tested were Epiphany and Evolution.  Other applications tested include gedit, gnome-calculator, gnome-terminal, firefox, chrome, konsole, gnome-music, gnome-builder, nautilus, gnome-font-viewer, gnome-shell.

Epiphany fails both on the WebkitGTK+ widget, and on a normal GTK+ widget.  It fails on both web content, and the URL bar.
