Thanks for the example, this helps us more. I confirm that I can
reproduce your bug. It seems as if the GtkTextView isn't refreshed
soon enough. The refresh of the animated gif appears to be having a
higher priority than the text view. I don't know if this is somehow
related: http://library.gnome.org/devel/gtk/stable/GtkTextView.html#GTK-TEXT-VIEW-PRIORITY-VALIDATE--CAPS.

You can force a redraw of the widget your self, in my case it fixed
the issue. Try the following:

Line 76:
  $view->scroll_mark_onscreen($textmark);
  $view->queue_draw();
