No. They. Don't.
New Radeons do not even HAVE specialized 2D units. Ditto for ALL embedded cards (from Poulsbo to Mali and Reno) - they sometimes have accelerated overlays, but never 2D drawing acceleration.
Besides, you've missed the part about threading - XRender in X.org works in a single thread for ALL clients. Do you think it's a good design?
> Ok. I can see that you don't know things you talk about. But I don't understand what are you really trying to say any more. This has nothing to do about Mir protocol, Wayland protocol, X11 protocol, their problems or limitations. Then what's this all about? Are you trolling? Or do you just like talking to me? ;-)
I think that X should be killed with fire as soon as possible. It was THE greatest stumbling block for Linux users for a long, long time (XF86Config - ugh).
