After a fresh Ubuntu-Gnome 14.10 install I wanted to use the Elegance-colors theme, I installed it via apt-get and set it with tweak tool and everything seems to work but the windows top bar (don't know how it's called) keeps the default round appearance, and not the flat square from the theme. I used this theme since 12.10 I think and this is the first time that this happens.
Any suggestion?
