The env variable SAL_USE_VCLPLUGIN seems to select which plugin from
/usr/lib/libreoffice/program/libvclplug_*lo.so
to load, maybe some sort of desktop integration driver.
In this case the plugin comes with the package
libreoffice-qt5
which seems to be compiled from the libreoffice source itself.
But still unclear whether this is a problem of this plugin itself or of that many Q5t libraries it is linked against.
