The default /etc/gtk-3.0/settings.ini file from gtk+ 3.12.2 refers to Adwita theme which is not installed on my system. Either gtk+ ebuild should depend on the package that provides the theme or, if the theme is provided by some large package that is a part of gnome settings.ini should point to a different theme. Reproducible: Always
This bug has effectively OBSOLETE status. First of all, in 3.12 Adwaita was a part of gnome-themes-standard, which was pretty much assumed by upstream to be installed. However, in 3.14 that whole theme was merged into gtk+ source tree.
It's also INVALID, setting it there will cause it to be used *if present*, if not, it will use another fallback (that was finally dropped in 3.14). It's more related to add another fallback before going directly with the ugly "default" theme

However, I am not sure it is a good idea to provide a configuration that may cause the look-n-feel change in the future when a user decides to install additional software.
The look&feel will be as ugly as when there is no default set there, the difference is that it will use the Adwaita theme for people that have it installed
