broken display for LibreOffice

Hello:
	[I have previously sent this to office@; now - not having heard
back - I cast a wider net.]

	On a system running:

FreeBSD 11.0-RC2 #0 r304729: Wed Aug 24 06:59:03 UTC 2016  amd64

	I built and installed libreoffice 5.0.6_3; everything seemed to
go OK.  (List of options is appended.) 

	However ... when I start it I get the image shown at:

http://jerusalem.litteratus.org:8888/~huff/LO.png

	Shortcut keys (e.g. Ctl-Q) work; if I move the mouse over the
screen I see the labels for the recent documents screen.  So it
looks like it's some sort of display problem.
	A search of the PR database shows nothing relevant.
	Help, please - How have I managed to mess this up?


			Respectfully,


				Robert Huff
