I seem to have a related problem with gtk3-demo. I'm not entirely certain, but I think there's a missing divider after the selection list on the left, and the actual demo. I also get this odd behaviour in Emacs, where the toolbar(?) is completely condensed. In gtk3-demo the tab-bar also seems to be a little... odd. gtk3-menu: https://i.imgur.com/7ytiQwK.png emacs: https://i.imgur.com/XDI8I6y.png I'm using OpenBox with the numix theme. Yesterday I did not have this problem, and I have not change the theme.
