Bug report

Bug summary

When running https://matplotlib.org/gallery/event_handling/path_editor.html#sphx-glr-gallery-event-handling-path-editor-py I get a recursion error.

Can anybody reproduce this?

Code for reproduction
Environment:

conda create -n test-path-editor matplotlib pyqt python=3.7

Matplotlib version

  • Operating system: Linux
  • Matplotlib version: Tested on master and 3.1.1 and 3.0.3
  • Matplotlib backend (print(matplotlib.get_backend())): Qt5Agg
  • Python version: 3.7
  • Other libraries: Qt 5.9.2

Actual outcome

RecursionError: maximum recursion depth exceeded in comparison

    I can repro. This appears to go back at least to mpl3.0(!) but doesn't happen with mplcairo.qt.

    2.2.4 still works.

    Are you sure 2.2.4 works? It doesn't work for me, but note it's Qt-backend specific. It works in 2.1.2 though, so a bisect says 984fba1 is the first bad commit
