I know some people here have run Compiz standalone, which IIRC is good for all kinds of eyecandy, including true transparency. Been a long time since I've seen any mention of it though.
Who doesn't like some eyecandy for their desktops, definitely not me. Compiz has enthralled Ubuntu users for years now. When GNOME officially ditched Compiz for Mutter for its next version, Ubuntu decided to stick with Compiz for its Unity Shell.
I really like the transparency effects in compiz with GNOME2 and wanted to know if there was any way (I'm assuming without using compizconfig) to have some kind of transparency in the windows. Is there something similar to compiz for GNOME3?
