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.
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.
Caolán McNamara committed a patch related to this issue.
It has been pushed to "master":
Resolves: tdf#102778 by default use breeze_dark when dark themes are requested
It will be available in 5.3.0.
The patch should be included in the daily builds available at
http://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More
information about daily builds can be found at:
Affected users are encouraged to test the fix and report feedback.
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.
