[Gretl-devel] Icons on Ubuntu 19.10 (Gtk / Yaru)

Hi, I'm currently trying out gretl on a Ubuntu 19.10 installation serving the screen via Broadway (browser-based). I see many icon warnings like this: (gretl_x11:1191): Gtk-WARNING **: 21:28:23.825: Error loading theme icon 'help-about' for stock: Icon 'help-about' not present in theme Yaru This is gtk3, obviously. I've seen such warnings and the missing icons on the experimental Windows builds, but not on Linux so far (I think). Not sure whether that's something gretl itself can solve. thanks sven
