This is only the case when `usetex=False` in `rcParams`.\r\n\r\n**Code for reproduction**\r\n\r\n```python\r\nimport matplotlib\r\nimport matplotlib.pyplot as plt\r\n\r\nfrom matplotlib import rc\r\nrc('text', usetex=False)\r\n\r\nfig, ax = plt.subplots(1,1)\r\nax.text(0.5, 0.5, '$S_{*} M^{ath}$ and some not math',\r\n         transform=ax.transAxes)\r\nplt.savefig('test1.png', bbox_inches='tight')\r\n```\r\n\r\n![test2](https://user-images.githubusercontent.com/4648092/65336879-07f14680-dbbf-11e9-9a0f-43fc495b20cc.png)\r\n\r\nYou can see the bottom of the text box is cut off. Whereas this plots fine:\r\n\r\n```python\r\nfig, ax = plt.subplots(1,1)\r\nax.text(0.5, 0.5, '$S_{ome} M^{ath}$ and some not math',\r\n         transform=ax.transAxes)\r\nplt.savefig('test1.png', bbox_inches='tight')\r\n```\r\n\r\n![test1](https://user-images.githubusercontent.com/4648092/65336976-32db9a80-dbbf-11e9-98bf-306e5166ad9b.png)\r\n\r\n\r\n**Matplotlib version**\r\n  * Operating system: Unix\r\n  * Matplotlib version: 3.1.1\r\n  * Matplotlib backend (`print(matplotlib.get_backend())`): TkAgg\r\n  * Python version: Python 3.6.8 (default, Apr 25 2019, 21:02:35)\r\n\r\nmatplotlib installed from pip\r\n\r\n  * Other libraries: \r\n\r\ncycler==0.10.0\r\nkiwisolver==1.1.0\r\nnumpy==1.17.2\r\npyparsing==2.4.2\r\npython-dateutil==2.8.0\r\nsix==1.12.0\r\n","author":{"url":"https://github.com/christopherlovell","@type":"Person","name":"christopherlovell"},"datePublished":"2019-09-20T14:58:34.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":20},"url":"https://github.com/15313/matplotlib/issues/15313"}
