Why don't you give it a try?
I am on Debian Gnu/Linux and Ubuntu repository, will not want to try. however, I will try with Linuxmint which I have.
@devels: since, debian/gnome bts is not taking care of this bugreport, I appreciate a word from You if this bug has the scope getting fixed sooner or later?
@lui75: thanks for the idea regarding cogl. so, libcogl5(clutter) may be the core issue with slow/garbled 3D rendering.
I have gone through gnome-shell-3.3.x mailing list details and I haven't read anywhere they fixed this bug in mutter. if You have, please share. also, gnome-shell/mutter is at 3.3.90 meaning an imminent release of Gnome-3.4(even number=release)
