Well, I pretty much got told where to stick it...

"Considering that Shutter is trying to use the X11 API, I'm wondering
why youthought it would work, or why you think GTK+ has anything to do

Wayland is fundamentally different than X11. You cannot grab the root

can only access the contents of the windows it created.

You should ask the Shutter developers to fix their application to work
under Wayland; sadly there is no common protocol to ask the Wayland
compositor to provide a screenshot. GNOME Shell has a DBus interface
