> Can you explain why you think that GTK is not ready for UI_SIDE_COMPOSITING? Efl guys have already refactored Qt's UI_SIDE_COMPOSITING code into reusable form, so Gtk port can simply reuse it.

The thing that's missing from this bug is the answer to the question "Why?" From my discussions with the Qt folks, I concluded that UI-side compositing was the solution to actual problems that they were facing. What is the goal for implementing this for GTK+ especially since we do not yet have full support for touch events? Wouldn't it be better to wait until we know this will solve actual problems? I think it's important to consider these questions, since UI-side compositing *greatly* increases the complexity of the code. Thus in my opinion, it's not appropriate to implement it for the sake of an educational exercise or simply because other ports do.
