For recent GTK 3 versions there is nothing to fix, 3.14 dropped
support for theme engines. You can only try to port the themes to
CSS...

...however that is not a one time effort, as noted earlier, in the
past every minor release introduced more or less breakage among
themes. And changes affecting themes are not specifically
documented, so you can only try to monitor changes to Adwaita and
work by trial and error.
