I have a number of figures which include graphics from matplotlib. They all previewed fine until I changed the mpl code to use:
import matplotlib as mpl
mpl.rc('font', family='stix')
mpl.rc('axes', labelsize='large')
I notice that mpl now warns that it cannot subset stix and includes the
whole font.
Anyway, now the figures render fine in the final pdf, but lyx preview is
broken with the above error message.
This is lyx-2.1.3 on fedora 22.
