Well, but you installed libreoffice-gtk3 manually. (Or do you have
libreoffice-gnome installed even for your xfce?) What do other users
of your desktop use?
But yeah, stuff like this is hard to debug.

They use xfce, too?
You don't need to, given you are the admin of the machine, not your wife
and your daughter.

Yes, there is.

There problem here AFAICS is that Xfce is also detected as GNOME somehow
(othwise you probably wouldn't even get Gtk2 UI)..
https://cgit.freedesktop.org/libreoffice/core/tree/vcl/unx/generic/plugadapt/salplug.cxx
But yes, we probably could add a new "fallback list" there just for Xfce.
But for now (you of course need libreoffice-gtk2 installed), try
export SAL_USE_VCLPLUGIN=gtk (export OOO_FORCE_DESKTOP=xfce probably won't work
given the "fallback list" above)
