The plot will not work and a Latex runtime error is thrown.\r\nIf you switch the commands everything works fine.\r\n\r\n**Code for reproduction**\r\n\r\n\u003c!--A minimum code snippet required to reproduce the bug, also minimizing the number of dependencies required--\u003e\r\n\r\n```python\r\nimport numpy as np\r\nimport matplotlib.pyplot as plt\r\nfrom matplotlib import ticker\r\n\r\ncbformat = ticker.ScalarFormatter(useMathText=True)\r\nplt.rc('text', usetex=True)\r\n\r\nplt.imshow(np.random.random((5, 5)))\r\nplt.colorbar(format=cbformat)\r\nplt.show()\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\nException in Tkinter callback\r\nTraceback (most recent call last):\r\n  File \"/usr/local/lib/python3.6/dist-packages/matplotlib/texmanager.py\", line 393, in make_dvi\r\n
