RIP Compiz. I liked it a lot. I wasn't a fan of the desktop cube or wobbly windows, but I liked the subtle effects. But I couldn't use it, because if I did, other things didn't work. Like cut 'n paste, buttons and menus. Things that really shouldn't stop working for mysterious reasons.
Gnome 3 has subtle effects and doesn't seem to have any bugs as calamitous as Compiz. Role on Wheezy!
