why do you detach and then re-attach the model to the view every 100ms, 
instead of just clearing/manipulating/appending the data in the store 
directly?

Call gtk_tree_model_row_changed() for each row for which you want to force a 
redraw (gtk_list_store_set() will do that automatically for you).

If that doesn't work, you are probably using the treeview in fixed height mode 
and ran into http://bugzilla.gnome.org/show_bug.cgi?id=136496
