This is a description of an apparent GTK3 (or Unity?) bug and a workaround I found after 2 days of hunting.

Problem description:
Main window has multiple tabs.
Tabs have drawing areas (among other widgets).
Select tab A and resize the window large (the size of the drawing area follows).
Select tab B and resize the window small (the size of the drawing area follows).
Open another app with another window elsewhere on the desktop.
Result: tab B expands by itself to the size left by tab A.

Workaround:
When the window with tab B selected is resized, set the drawing area size in tab A to a very small size. This prevents the future auto expansion of tab B. When tab A is selected, the drawing area is resized to match the window containing it.

Versions:
GTK 3.6.0
Ubuntu 12.10
