Created attachment 6844 clipman icon CLOSEUP Since 1.4.0 the icon is near invisible against a dark panel. Changing icon themes make no difference.
Hi, clipman now uses Gtk3's "symbolic icons", which means that the colors of the icon are determined by the Gtk theme in use. If your theme has decent Gtk3 support correctly sets the foreground color of the panel the icon will look fine. Could you please try with the Greybird (https://github.com/shimmerproject/Greybird) version fitting your Gtk3 release and test again? Thanks! As an additional note: I'm planning to make this feature optional.
Using Adwaita (the Gtk default) this problem does not exist, so it's probably a theme or icon theme issue.
