According to @ImportanceOfBeingErnest, this issue is related to [#10088](https://github.com/matplotlib/matplotlib/pull/10088).\r\n\r\nI include a minimal code fragment that demonstrates the problem.\r\n\r\n**Code for reproduction**\r\n\r\n\u003c!--A minimum code snippet required to reproduce the bug.\r\nPlease make sure to minimize the number of dependencies required, and provide\r\nany necessary plotted data.\r\nAvoid using threads, as Matplotlib is (explicitly) not thread-safe.--\u003e\r\n\r\n```python\r\nfrom matplotlib import pyplot as plt\r\nplt.plot([0, 1], [8, 6])\r\nax = plt.gca()\r\nyticks = ax.get_yticklabels()\r\nprint(yticks)\r\nfor tick in yticks:\r\n    tick.set_visible(False)\r\n\r\nprint(ax.get_yticklabels())\r\n```\r\n\r\n**Actual outcome**\r\n\r\n\u003c!--The output produced by the above code, which may be a screenshot, console output, etc.--\u003e\r\n\r\n```\r\n\u003ca list of 11 Text yticklabel objects\u003e\r\n\u003ca list of 0 Text yticklabel objects\u003e\r\n```\r\n\r\n**Expected outcome**\r\n\r\nThe snippet shows that the y tick labels are destructed after setting their visibility to False. One can restore them by issuing:\r\n```\r\nax.yaxis.set_tick_params(labelleft=True)\r\n```\r\nThis issue first occurred on matplotlib 3.1.2 but not on the previous version (which I believe was 3.0.x).\r\n\r\n\u003c!--A description of the expected outcome from the code snippet--\u003e\r\n\u003c!--If this used to work in an earlier version of Matplotlib, please note the version it used to work on--\u003e\r\n\r\n**Matplotlib version**\r\n\u003c!--Please specify your platform and versions of the relevant libraries you are using:--\u003e\r\n  * Operating system: Win10 Pro 64bit\r\n  * Matplotlib version: 3.1.2\r\n  * Matplotlib backend (`print(matplotlib.get_backend())`): Qt5Agg\r\n  * Python version: 3.6.3\r\n\r\n\u003c!--Please tell us how you installed matplotlib and python e.g., from source, pip, conda--\u003e\r\n\u003c!--If you installed from conda, please specify which channel you used if not the default--\u003e\r\nPython was installed via WinPython; Matplotlib was manually upgraded to v3.1.2.\r\n","author":{"url":"https://github.com/TheAngulion","@type":"Person","name":"TheAngulion"},"datePublished":"2020-01-12T17:35:17.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":7},"url":"https://github.com/16197/matplotlib/issues/16197"}
