My apparent bias is because I have never had a dedicated GPU since the golden days of 3DFx, only laptops with built-in mostly-Intel graphics. Compiz apparently was not made for these. And the only week I had a PC with a full-blown nVidia GPU in my disposition it was bleeding-edge new so no driver worked well with it. One lesson (or whatever you call it when you learn something questionable because of the inherent bias in the circumstances) my whole life has been teaching me is 3D acceleration is always about bugs and quirks, often also about slowness and I hardly want these in my window manager. And now as I am transitioning into an old fart, I dream of my whole UI to look like an zen-boring e-Ink eBook reader rather than a wobbly&colorful bells&whistles flying circus :-] Surely I agree the MacOS DE could use a lot of customizations to allow though.
