@szydell How did you get that window_decorations.css?
On my desktop, ls .config/gtk-3.0/ bookmarks servers settings.ini
And starting gpick from terminal: ``gpick
(gpick:19694): Gtk-CRITICAL **: 00:54:18.583: gtk_widget_get_scale_factor: assertion 'GTK_IS_WIDGET (widget)' failed``
@duffy It turned out a bug related to a typo inside the Makefile tarball causing the wallpaper failing to display on some desktop environments. https://bugzilla.redhat.com/show_bug.cgi?id=1885792 The fix is on the way.
