That was it! But not the way I think you expected. I was sure I wasn't
using a compositor, but when I read this a second time I suddenly
noticed that the feathered gray borders that I had around windows were
missing. So I went into the Xfce Settings Manager and in the Window
Manager Tweaks dialog window there is a tab for Compositor. I found
that the checkbox there for "Show shadows under dock windows" was
unchecked. I checked it and instantly the shadows came back. And when I
tried LibreOffice and Claws mail all the missing lists and menu text
was back.

So the problem is solved, although I have no idea why LO and CM need
the compositor to display menus and lists. That makes no sense to me.
But in any event, thanks for writing that because it made my brain look
at something I should have seen from the beginning. :)
