Bug summary

Creating a plot inside of matplotlib.pyplot.rc_context and then calling matplotlib.pyplot.show() outside said context causes the program to freeze.

Code for reproduction

import matplotlib.pyplot as plt

with plt.rc_context():
    plt.plot([1, 3, 2])

plt.show()

Actual outcome

The program freezes.

Expected outcome

The plot is shown.

Additional information

• matplotlib.pyplot.savefig() works as expected.
• The bug did not occur in earlier versions.
• The bug does not occur when using Jupyter, only when using the regular Python interpreter.
• The bug does not occur if plt.show() is called inside of plt.rc_context.
