The GtkDial part of the tutorial is deprecated and should
not be used when writing new widgets[*].  It is not GObject
based at all, it uses functions like gtk_widget_draw() and
IIRC the widget is functionally broken too.

I suggest to read the text with a grain of salt, ignoring
the code altogether and looking at the corresponding code of
a real modern Gtk+ widget instead.

a paraphrase of what Gtk+ documentation says about the
methods used.

I don't observe anything like this.  However the dial
pointer is drawn with gtk_draw_polygon() (another deprecated
function), therefore the look can be very theme dependent.
