I have noticed that as well on GTK+ 3 a year ago or so, and I don't think this is specific to GtkTreeView.  Back then I got the impression that some parts of the drawing "synchronization" (i.e. draw the moved area and the newly exposed area at the same time instead of first drawing the moved area and drawing the newly exposed area later) did not make it into the client-side-windows code.  However, I was told that such problem should not exist with client side windows (I was not convinced though).
