So either the PDF backend does not correctly mark itself as not supporting blitting, or the blitting is not turned off correctly in the button widgets.\n\n### Code for reproduction\n\n```python\nmake -C doc latexpdf\n```\n\n\n### Actual outcome\n\n```pytb\r\n/home/elliott/code/matplotlib-3.7.x/doc/users/next_whats_new/widget_button_styling.rst:8: WARNING: Exception occurred in plotting widget_button_styling-1\r\n from /home/elliott/code/matplotlib-3.7.x/doc/users/next_whats_new/widget_button_styling.rst:\r\nTraceback (most recent call last):\r\n  File \"/home/elliott/code/matplotlib-3.7.x/lib/matplotlib/sphinxext/plot_directive.py\", line 615, in render_figures\r\n    figman.canvas.figure.savefig(img.filename(fmt), dpi=dpi)\r\n  File \"/home/elliott/code/matplotlib-3.7.x/lib/matplotlib/figure.py\", line 3328, in savefig\r\n    self.canvas.print_figure(fname, **kwargs)\r\n  File \"/home/elliott/code/matplotlib-3.7.x/lib/matplotlib/backend_bases.py\", line 2362, in print_figure\r\n    result = print_method(\r\n             ^^^^^^^^^^^^^\r\n  File \"/home/elliott/code/matplotlib-3.7.x/lib/matplotlib/backend_bases.py\", line 2228, in \u003clambda\u003e\r\n    print_method = functools.wraps(meth)(lambda *args, **kwargs: meth(\r\n                                                                 ^^^^^\r\n  File \"/home/elliott/code/matplotlib-3.7.x/lib/matplotlib/backends/backend_pdf.py\", line 2815, in print_pdf\r\n    self.figure.draw(renderer)\r\n  File \"/home/elliott/code/matplotlib-3.7.x/lib/matplotlib/artist.py\", line 95, in draw_wrapper\r\n    result = draw(artist, renderer, *args, **kwargs)\r\n             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^\r\n  File \"/home/elliott/code/matplotlib-3.7.x/lib/matplotlib/artist.py\", line 72, in draw_wrapper\r\n    return draw(artist, renderer)\r\n           ^^^^^^^^^^^^^^^^^^^^^^\r\n  File \"/home/elliott/code/matplotlib-3.7.x/lib/matplotlib/figure.py\", line 3135, in draw\r\n    DrawEvent(\"draw_event\", self.canvas, renderer)._process()\r\n  File \"/home/elliott/code/matplotlib-3.7.x/lib/matplotlib/backend_bases.py\", line 1259, in _process\r\n    self.canvas.callbacks.process(self.name, self)\r\n  File \"/home/elliott/code/matplotlib-3.7.x/lib/matplotlib/cbook/__init__.py\", line 309, in process\r\n    self.exception_handler(exc)\r\n  File \"/home/elliott/code/matplotlib-3.7.x/lib/matplotlib/cbook/__init__.py\", line 96, in _exception_printer\r\n    raise exc\r\n  File \"/home/elliott/code/matplotlib-3.7.x/lib/matplotlib/cbook/__init__.py\", line 304, in process\r\n    func(*args, **kwargs)\r\n  File \"/home/elliott/code/matplotlib-3.7.x/lib/matplotlib/widgets.py\", line 1706, in _clear\r\n    self.ax.draw_artist(self._buttons)\r\n  File \"/home/elliott/code/matplotlib-3.7.x/lib/matplotlib/axes/_base.py\", line 3076, in draw_artist\r\n    a.draw(self.figure.canvas.get_renderer())\r\n           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^\r\nAttributeError: 'FigureCanvasPdf' object has no attribute 'get_renderer'\r\n```\n\n### Expected outcome\n\nDocs build without warning.\n\n### Additional information\n\n_No response_\n\n### Operating system\n\nFedora 37\n\n### Matplotlib Version\n\nv3.7.x\n\n### Matplotlib Backend\n\nPDF\n\n### Python version\n\n3.11.1\n\n### Jupyter version\n\n_No response_\n\n### Installation\n\ngit checkout","author":{"url":"https://github.com/QuLogic","@type":"Person","name":"QuLogic"},"datePublished":"2023-01-25T08:35:50.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/25075/matplotlib/issues/25075"}
