If I use
gtk_style_context_add_class(context, "header");
As I replied, I fixed that problem to call
this.get_style_context().remove_class("csd") after set_titlebar(header) is
called.

The background drawn to the event box window is transparent on my computer. I just used
"menu" to test a different color from the theme but there are
many that you can test. The style classes are at the bottom of the
documentation page.
https://developer.gnome.org/gtk3/stable/GtkStyleContext.html
I painted the main window green so that I could see if the event box window
gets drawn to and also to distinguish widgets that don't have windows like
the GtkLabel, GtkBox and GtkGrid.
Another option is to have a CSS file for the header widget and use that
although then you get away from using the users theme. I have tried using the
deprecated function
gtk_style_context_get_background_color()
to peak at if there is a constant background color set and what it might be but
that function isn't going to work for a gradient or image so it is
only a partial solution for checking the style class background.
Still trying to figure out these things myself.
