I see this on macOS (both M1 and Intel) and have not managed to reproduce this in a few other container environments I tried.\r\n\r\n### Code for reproduction\r\n\r\n```python\r\nimport matplotlib.pyplot as plt\r\nplt.figure()\r\n```\r\n\r\n\r\n### Actual outcome\r\n\r\n```\r\n/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.\r\n  plt.figure()\r\n```\r\n\r\n### Expected outcome\r\n\r\nno warning raised\r\n\r\n### Additional information\r\n\r\nI 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:\r\n```bash\r\n/tmp/mpl ❯ ls\r\n/tmp/mpl ❯ pipx run virtualenv venv\r\ncreated virtual environment CPython3.10.4.final.0-64 in 159ms\r\n  creator CPython3Posix(dest=/private/tmp/mpl/venv, clear=False, no_vcs_ignore=False, global=False)\r\n  seeder FromAppData(download=False, pip=bundle, setuptools=bundle, wheel=bundle, via=copy, app_data_dir=/Users/alheld/Library/Application Support/virtualenv)\r\n    added seed packages: pip==22.2.2, setuptools==65.3.0, wheel==0.37.1\r\n  activators BashActivator,CShellActivator,FishActivator,NushellActivator,PowerShellActivator,PythonActivator\r\n/tmp/mpl ❯ source venv/bin/activate\r\n/tmp/mpl ❯ python --version\r\nPython 3.10.4\r\n/tmp/mpl ❯ which python\r\n/private/tmp/mpl/venv/bin/python\r\n/tmp/mpl ❯ pip install matplotlib\r\nCollecting matplotlib\r\n  Using cached matplotlib-3.6.0-cp310-cp310-macosx_11_0_arm64.whl (7.2 MB)\r\nCollecting pillow\u003e=6.2.0\r\n  Using cached Pillow-9.2.0-cp310-cp310-macosx_11_0_arm64.whl (2.8 MB)\r\nCollecting numpy\u003e=1.19\r\n  Using cached numpy-1.23.3-cp310-cp310-macosx_11_0_arm64.whl (13.3 MB)\r\nCollecting packaging\u003e=20.0\r\n  Using cached packaging-21.3-py3-none-any.whl (40 kB)\r\nCollecting python-dateutil\u003e=2.7\r\n  Using cached python_dateutil-2.8.2-py2.py3-none-any.whl (247 kB)\r\nCollecting cycler\u003e=0.10\r\n  Using cached cycler-0.11.0-py3-none-any.whl (6.4 kB)\r\nCollecting fonttools\u003e=4.22.0\r\n  Using cached fonttools-4.37.2-py3-none-any.whl (959 kB)\r\nCollecting contourpy\u003e=1.0.1\r\n  Using cached contourpy-1.0.5-cp310-cp310-macosx_11_0_arm64.whl (226 kB)\r\nCollecting pyparsing\u003e=2.2.1\r\n  Using cached pyparsing-3.0.9-py3-none-any.whl (98 kB)\r\nCollecting kiwisolver\u003e=1.0.1\r\n  Using cached kiwisolver-1.4.4-cp310-cp310-macosx_11_0_arm64.whl (63 kB)\r\nCollecting six\u003e=1.5\r\n  Using cached six-1.16.0-py2.py3-none-any.whl (11 kB)\r\nInstalling collected packages: six, pyparsing, pillow, numpy, kiwisolver, fonttools, cycler, python-dateutil, packaging, contourpy, matplotlib\r\nSuccessfully installed contourpy-1.0.5 cycler-0.11.0 fonttools-4.37.2 kiwisolver-1.4.4 matplotlib-3.6.0 numpy-1.23.3 packaging-21.3 pillow-9.2.0 pyparsing-3.0.9 python-dateutil-2.8.2 six-1.16.0\r\n/tmp/mpl ❯ python -c \"import matplotlib.pyplot as plt; import matplotlib as mpl; print(mpl.__version__); plt.figure()\"\r\n3.6.0\r\n\u003cstring\u003e:1: MatplotlibDeprecationWarning: The resize_event function was deprecated in Matplotlib 3.6 and will be removed two minor releases later.
