I don't know what Socket and Plug is...

But you seems to do the drawing completely wrong.

Generally gtk_widget_queue_draw() is involved in the drawing process,
that is that your timer does not do the drawing directly, but only
invalidates the widget, which cause a indirect draw.

You may find a few examples for this, one recent using plain C was
contained in this thread:
