I have noticed few other issues -
1. When SwingSet2 is visible on the screen, I am pushing the command prompt to FS mode and restoring to enforce a surface loss. Doing this a few times makes some of the components appear black.
2. Push the command prompt to FS mode and restore it. After that, move the SwingSet2 from one screen to the other. The entire UI becomes garbled.
