This has always been the default, but #6287 proposes a change to a new option, which triggers the failure.  Modifying the example to change `axisbelow` to `True` also triggers it, with the following traceback:\n\n```\n(test)efiring@manini2:~/work/programs/py/mpl/matplotlib/examples$ python api/custom_scale_example.py\nTraceback (most recent call last):\n  File \"/Users/efiring/anaconda/envs/test/lib/python3.5/site-packages/matplotlib/backends/backend_qt5agg.py\", line 179, in __draw_idle_agg\n    FigureCanvasAgg.draw(self)\n  File \"/Users/efiring/anaconda/envs/test/lib/python3.5/site-packages/matplotlib/backends/backend_agg.py\", line 464, in draw\n    self.figure.draw(self.renderer)\n  File \"/Users/efiring/anaconda/envs/test/lib/python3.5/site-packages/matplotlib/artist.py\", line 68, in draw_wrapper\n    return draw(artist, renderer, *args, **kwargs)\n  File \"/Users/efiring/anaconda/envs/test/lib/python3.5/site-packages/matplotlib/figure.py\", line 1262, in draw\n    renderer, self, dsu, self.suppressComposite)\n  File \"/Users/efiring/anaconda/envs/test/lib/python3.5/site-packages/matplotlib/image.py\", line 139, in _draw_list_compositing_images\n    a.draw(renderer)\n  File \"/Users/efiring/anaconda/envs/test/lib/python3.5/site-packages/matplotlib/artist.py\", line 68, in draw_wrapper\n    return draw(artist, renderer, *args, **kwargs)\n  File \"/Users/efiring/anaconda/envs/test/lib/python3.5/site-packages/matplotlib/axes/_base.py\", line 2361, in draw\n    mimage._draw_list_compositing_images(renderer, self, dsu)\n  File \"/Users/efiring/anaconda/envs/test/lib/python3.5/site-packages/matplotlib/image.py\", line 139, in _draw_list_compositing_images\n    a.draw(renderer)\n  File \"/Users/efiring/anaconda/envs/test/lib/python3.5/site-packages/matplotlib/artist.py\", line 68, in draw_wrapper\n    return draw(artist, renderer, *args, **kwargs)\n  File \"/Users/efiring/anaconda/envs/test/lib/python3.5/site-packages/matplotlib/axis.py\", line 1142, in draw\n    self.label.draw(renderer)\n  File \"/Users/efiring/anaconda/envs/test/lib/python3.5/site-packages/matplotlib/artist.py\", line 68, in draw_wrapper\n    return draw(artist, renderer, *args, **kwargs)\n  File \"/Users/efiring/anaconda/envs/test/lib/python3.5/site-packages/matplotlib/text.py\", line 762, in draw\n    raise ValueError(\"posx and posy should be finite values\")\nValueError: posx and posy should be finite values\n```\n","author":{"url":"https://github.com/efiring","@type":"Person","name":"efiring"},"datePublished":"2016-04-18T01:40:20.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/6312/matplotlib/issues/6312"}
