Oh, yeah: If you just want to try something to get this working, try
setting the verbosity level:
import matplotlib
matplotlib.verbose.set_level('debug')
Assuming this is the same issue as PR 989, redirecting stdout to the
command line will prevent the buffer issues. (You'll get a lot of debug
output printed to the command line, though).
Hope that helps,
