--- Comment #9 from Pekka Paalanen <ppaalanen at gmail.com> ---
I do not think toolkits will ever bother optimizing for the case of an empty
window. There is just no use for it.

Besides, if the window has resizing handles or any decorations, it may not be
empty: the window decorations might be drawn in the same buffer (the default on
Gnome and Gtk+ AFAIK). This prevents sharing the buffer storage, and disallows
the use of the wl_viewport trick.

Closing as wontfix.

If you want near zero CPU-usage for window resizing, you'll get that with a
compositor that implements either outline or GL-texture-scaled resizing instead
of live resizing, regardless of window content. That could actually have a use.
