Yes. We resize the GtkFixed where the text-part and scrollbar resides in Emacs. 
The layout widgets can not handle the layout of Emacs (i.e. text with 
scrollbar, modeline without scrollbar, minibuffer with scrollbar). If the 
scrollbar is 16 pixels wide no matter what, and Emacs thinks it. is 12, the 
sizing will be wrong.

You have to add 2 x trough-border, i.e 2 x 1.
