Hmmm, there seems to be a slight change in behavior but there is still massive flickering. I wonder though, the window gets updated even when I tell it not to with gdk_window_freeze_updates() without its thaw counterpart. Is this supposed to happen? Is it reseted in the gtk main loop? I guess the easiest solution might be to change container. Is there any container that does exactly the same job as GtkList? That allows for me to stick boxes into listItems? I have to stick like 14 widgets per item including some labels and entries I think the CList doesnt allow for you to stick boxes into it. If it does, I don't understand how.

I've seen gtk_clist_freeze and gtk_clist_thaw which is a good sign but....  :).
