I'm using Xubuntu 19.04 and sometimes when I click around in GTK apps I can see a dotted outline around elements such as buttons. I understand this is here for people who want to use a keyboard to navigate around an app, but I never do that and I hate the way it looks.
Is there a way I can disable this, maybe by adding something to my ~/.config/gtk-3.0/gtk.css file?
I did have a brief look around and I tried to add this to it:
gtk_widget_get_can_focus (GtkWidget *button);
but I've had no luck. I'm assuming it's really not the right way to do it, and probably not even the right use of the command.
Any help with this would be seriously appreciated. It's driving me insane!
