How do I take a screenshot in dom0 while the menu is open?

As for screenshots with menu open, the xfce screenshot tool has an option to take screenshot with a delay (run it without arguments - xfce4-screenshooter, I have it bound to ctrl+prnscr, but that’s my custom setting), and then you should be able to capture open menu.
