Please, tell what is your platform, under which system. Which Python 
You seem not believing me that you may have conflicts between various QT 
instances. Perhaps...  Verify *all* the occurrences of your libraries 
susceptible of being used by the mpl backend variants. Use 'which', 
'where', 'locate', etc., all that goes on your system.
First of all, you must ensure and be certain that you launch what you 
think you do, and not some "parasites".
BTW. I didn't use "show()" for a long time, plt.plot(...) plots, and 
that's it.

All the best
