Wickid Designs

I’m using the theme Ambiance, I edited its file directly at:

/usr/share/themes/Ambiance/gtk-2.0/gtkrc

style "menu-item" = "menu"
{
        xthickness = 0
        ythickness = 5

        engine "murrine"
        {
                roundness = 0
        }
}

To:

style "menu-item" = "menu"
{
        xthickness = 0
        ythickness = 0

        engine "murrine"
        {
                roundness = 0
        }
}
