This is not an issues with the previous 3.7.3 version or when backend is set to TkAgg.\n\n### Code for reproduction\n\n```python\nimport matplotlib\r\nimport matplotlib.pyplot as plt\r\nimport numpy as np\r\n\r\nfrom matplotlib import cm\r\n\r\n# matplotlib.use(backend=\"TkAgg\")\r\n\r\nplt.style.use(\"_mpl-gallery\")\r\n\r\n# Make data\r\nX = np.arange(-5, 5, 0.25)\r\nY = np.arange(-5, 5, 0.25)\r\nX, Y = np.meshgrid(X, Y)\r\nR = np.sqrt(X**2 + Y**2)\r\nZ = np.sin(R)\r\n\r\n# Plot the surface\r\nfig, ax = plt.subplots(subplot_kw={\"projection\": \"3d\"})\r\nax.plot_surface(X, Y, Z, vmin=Z.min() * 2, cmap=cm.Blues)\r\n\r\nax.set(xticklabels=[], yticklabels=[], zticklabels=[])\r\n\r\nplt.show(block=False)\r\n\r\ninput(\"Hit [return] to end\")\r\nplt.close(\"all\")\n```\n\n\n### Actual outcome\n\nNo plot is generated.\r\n\n\n### Expected outcome\n\n![Figure_1](https://github.com/matplotlib/matplotlib/assets/131495172/b4ba7774-f2fc-4da1-85e6-bb9200802f11)\r\n\n\n### Additional information\n\nIf the code line\r\n# matplotlib.use(backend=\"TkAgg\")\r\nis uncommented the code will work as expected.\n\n### Operating system\n\nMac OS 13.5.2\n\n### Matplotlib Version\n\n3.8.0\n\n### Matplotlib Backend\n\nMacOSX\n\n### Python version\n\n3.11.5\n\n### Jupyter version\n\n_No response_\n\n### Installation\n\nconda","author":{"url":"https://github.com/CarrascoCesar","@type":"Person","name":"CarrascoCesar"},"datePublished":"2023-09-22T16:22:04.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/26869/matplotlib/issues/26869"}
