            Bug ID: 164985
           Summary: [GTK] Multiple WebkitGTK+ windows of the same
                    application slow down
    Classification: Unclassified

Running multiple Epiphany windows on different workspaces causes severe slowdown of all Epiphany windows.

Environment: Gnome-Shell on Wayland

Running multiple windows, where the windows are on a different workspace, cause the windows to appear frozen.  To unfreeze them it's necessary to provide each window time to update it's contents.  In other words: it's necessary to switch to each workspace that has a Epiphany window before the window is updated.

1. Start Epiphany on workspace 1
2. Start a new window, or detach a tab
3. Move that window to workspace 2
4. Load a page (bugs.webkit.org) on workspace 1
5. Go to workspace 2
6. Attempt to update the URL bar
   ... no/slow update
7. Go to workspace 1
8. Go to workspace 2
   ... updated

I haven't been able to confirm that this happens with an application other than Epiphany.

This is likely related to # 164983 since it's similarly required to focus the other workspaces to receive an update.
