today I've updated GL and DRI libs to development state...
yeah here is the perfect appearance of Gnome-Shell!!
now Gnome-Shell/Unity-3D/Mutter works perfectly without fglrx's GL driver. what a fantastic!! :)
so for a meanwhile I would dive into radeon open-sourced driver. Gallium3D is quite fast and smoothly I've never seen on any other GPU... yeah so far from damned issues.
and finally, the most important thing is the radeon is the "KMS" driver. I hope it would work with Wayland! yep it's around time to say good-bye to Xorg.
I'm in love to radeon driver at all... :P
