It is NOT fixed in gnome-terminal 3.18.3. Here's my fix for the Ambiant-MATE theme:
toor@ubuntu:/usr/share/themes/Ambiant-MATE/gtk-3.0$ cat gtk.css TerminalWindow .notebook tab.top:active { font: bold; background-color: alpha(grey, 0.0); } TerminalWindow .notebook tab.top { background-color: alpha(grey, 0.4); } @import url("gtk-main.css"); -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-themes in Ubuntu. https://bugs.launchpad.net/bugs/1399734 Title: Current tab is not highlighted Status in ubuntu-themes package in Ubuntu: Confirmed Bug description: With the Ambiance or Radiance theme, in windows using a GtkNotebook the current tab is not highlighted to distinguish it from hidden tabs. In some apps you can just about see a faint line under the inactive tabs, but some apps, such as roxterm, don't use the border option, so it's impossible to tell which tab is selected.
