[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

I also see this on the first call to even as something simple as
plt.plot([0, 1], [0, 1]).andersgs commentedon Sep 17, 2022

This will be fixed in 3.6.1. For major releases like 3.6, the bug fix release is usually relatively soon.
YaolinGe commentedon Dec 21, 2022
It still happens on 3.6.2 on my mac in PyCharm Pro IDE.
Any updates?
tacaswell commentedon Dec 21, 2022
@YaolinGe I can not reproduce this outside of pycharm. Can you produce not launched through pycharm? If so can you please open a new issue?
YaolinGe commentedon Jan 5, 2023
@tacaswell I cannot reproduce this neither outside of pycharm. So it is a pycharm issue?
tacaswell commentedon Jan 5, 2023
Yes, please report this to jetbrains.
They have their own backend which may be the call site.

I received similar MatplotlibDeprecationWarning when using pp.close(_fig):
MatplotlibDeprecationWarning: The close_event function was deprecated in Matplotlib 3.6 and will be removed two minor releases later. Use callbacks.process('close_event', CloseEvent(...)) instead.
I am using WSL1, python 3.11.1, matplotlib==3.6.2 and matplotlib.use('nbAgg').
I was not able to find any instructions how to close the figure differently.
