So per second, about 2 or 4 displayed \"seconds\" are passing in the animation window with the animation processing significantly faster as expected. \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\nThe example was not changed.\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: Linux version 4.20.3-arch1-1-ARCH (builduser@heftig-25602) (gcc version 8.2.1 20181127 (GCC)) #1 SMP PREEMPT Wed Jan 16 22:38:58 UTC 2019\r\n\r\n  * Matplotlib version: 3.0.2\r\n  * Matplotlib backend: TkAgg\r\n  * Python version: 3.7.2\r\n  * Other libraries: Numpy: 1.16.0\r\n                             Scipy: 1.2.0\r\n\r\n\u003c!--Please tell us how you installed matplotlib and python e.g., from source, pip, conda--\u003e\r\nI installed Python from the Arch repositories.
