Specific examples:
(1) Open a drop-down menu in a GTK app and verify it looks the right size.
(2) Hover over some elements that will pop up a tooltip and to verify the tooltip is a sane size.
(3) xclock -geometry 100x100
(4) Run 'zenity --scale' and verify the default window size fits neatly around the widgets like in X.
I think you've probably fixed all this recently but it's mostly been discussed in bug 1543467 as mentioned above.
