• A lot of issues with the Mutter have been corrected;

• The GTK3 components have been improved;
There are also a lot of known bugs. For example, the IDE software Eclipse/Aptana may have some strange color bugs. Also, Ubuntu 13.04 uses a lot of Gnome 3.6 elopements, so for now there are still problems with the theme.
The theme has two requirements: GTK2 engine Murrine 0.98.1.1 or later and GTK2 pixbuf engine or the gtk(2)-engines package.
