Created attachment 127711 [details] Screenshot with Adwaita Dark - Ubuntu 16.10 Beta amd64 - LibreOffice 1:5.2.1~rc2-0ubuntu1 (Ubuntu package) which now defaults to GTK3 in Ubuntu 16.10+ - gnome-themes-standard 3.20.2-3ubuntu1 This screenshot was taken with GTK+ 3.22.0-0ubuntu1~yakkety0 from the GNOME3 Staging PPA although I believe it affects Ubuntu's GTK 3.20 also. There is not enough contrast in the symbolic icons in the bottom status bar with a dark theme which makes them difficult to see. I set the theme to Adwaita but I used gnome-tweak-tool to enable the "Global Dark Theme" option. Screenshot attached.
These are just pngs so there isn't a oneliner fix anyway and its not really gtk3 specific as I look at how they work
Here's what I suggest, basically as briefly discussed on the mailing list recently... If the dark variant of the gtk theme is requested (or if an icon theme is selected in gnome which is suffixed "dark") then by default fallback in LibreOffice to our only dark icon theme.

Best I can do for now until we move to something like using svg icons sources with symbolic color names we can replace with the theme colors.
