Fullcolor icons removed from adwaita-icon-theme
Since adwaita-icon-theme 42.0, the fullcolor icons are no longer available:
It causes that some icons are missing from the categories in the Application menu, and the rest are symbolic. The same goes for the status icons.
Possible solutions:
- Add the full color icons used by GNOME Flashback to this project from the old version of Adwaita icon theme, and use it as a fallback.
- Set another icon theme as default in the gschema.override file.
