... looks like what you see in the pic when Settings>Look>Application Theme> Icons >Enable icon themes (both options) are unchecked
This is how it looks with terminology 0.4 and all the official release stuff. I use a gnome icon set on this and have Settings>Look>Application Theme> Icons >Enable icon theme for applications checked.
Feel free to reassign it to the appropriate person.
is happening with any icon theme but with incomplete theme i think is permanent
open settings in terminology then go on elementary config and change rendering engine
will be no icons on elementary settings and also on terminology settings
