For example, subscript + is shown correctly even for dpi=600, while subscript - or * are not shown correctly and the previous letter is cut off. This is similar to #4428, so apparently the issue has not been resolved.\r\nExample:\r\n```\r\nimport matplotlib.pyplot as plt\r\nfig1 = plt.figure()\r\nax1 = fig1.add_subplot(111)\r\nax1.axis([0, 5, 0, 5])\r\nax1.text(2,4, '$X_-$', fontsize=25)\r\nax1.text(4,4, '$X_+$', fontsize=25)\r\nax1.text(2,2, '$X_*$', fontsize=25)\r\n\r\nfig2 = plt.figure(dpi=600)\r\nax2 = fig2.add_subplot(111)\r\nax2.axis([0, 5, 0, 5])\r\nax2.text(2,4, '$X_-$', fontsize=25)\r\nax2.text(4,4, '$X_+$', fontsize=25)\r\nax2.text(2,2, '$X_*$', fontsize=25)\r\n```\r\nproduces\r\n![correct](https://user-images.githubusercontent.com/62450716/98260326-7d66d480-1f83-11eb-991b-cec0de871ea3.png)\r\n![error](https://user-images.githubusercontent.com/62450716/98260342-80fa5b80-1f83-11eb-9aa8-8fd7a0aa7802.png)\r\n\r\nI am using matplotlib 3.3.2 with Python 3.7.8.\r\n","author":{"url":"https://github.com/swish42","@type":"Person","name":"swish42"},"datePublished":"2020-11-05T15:31:04.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/18899/matplotlib/issues/18899"}
