I had a similar problem rendering JPopup menus as a result of an event generated by a pickBehaviour. Heavyweight popups work fine but lightweight popups struggle to paint. The solution I used was to use the swing utility method SwingUtilities.invokeAndWait(runnableObject). This works fine for swing popups.
