[Bug]: resize_event deprecation warnings when creating figure on macOS with version 3.6.0 #23921
Description
Bug summary
Creating a figure via plt.figure() with matplotlib version 3.6.0 results in a MatplotlibDeprecationWarning. I see this on macOS (both M1 and Intel) and have not managed to reproduce this in a few other container environments I tried.
Code for reproduction
import matplotlib.pyplot as plt
plt.figure()Actual outcome
/private/tmp/mpl/test.py:3: MatplotlibDeprecationWarning: The resize_event function was deprecated in Matplotlib 3.6 and will be removed two minor releases later. Use callbacks.process('resize_event', ResizeEvent(...)) instead.
plt.figure()
Expected outcome
no warning raised
Additional information
I have not managed to reproduce this in any containers, so perhaps this is specific to the macosx backend. No warnings appear in earlier versions. I can reproduce the behavior also in new conda environments and virtual environments, here is a full example:
/tmp/mpl ❯ ls
/tmp/mpl ❯ pipx run virtualenv venv
