white border between titlebar and menubar in some applications

[offlineric]

not sure if this is just due to the gnome-team ppa being what it is on ubuntu or the style itself. here's a picture of what i'm talking about

it also happened in firefox but i was able to fix that in the userstyle.css

Probably due to GTK 2, I can't reproduce the issue for Firefox. Will look into it though.
EDIT: I installed the PA Equalizer and I can definitely see the problem. However, every other GTK2 theme I have tried apart from Zukitwo and Zukini have the same issue, which leads me to believe that it has to do with the engine Adwaita uses for the menubar. Overall the GTK 2 aspect of the theme is a real mess at the moment, so many issues are to be expected on that side, unfortunately. Will most likely be fixed when I get around to working on #2.
