White background fills entire output cell for Matplotlib plots

When I make a simple matplotlib plot, there is a white background covering the entire output cell area, which is pretty jarring in dark themes. I would expect it to only be white in the area immediately behind the figure. Also, I’m not sure why there is a small dark cutout in the lower right corner of the white background.

I’m guessing that it’s built this way because by default, the figure background is transparent. However, even if the plot image was partially transparent, I would not expect that to affect any parts of the screen beside the image itself, so this might be undesirable behavior.

Steps to reproduce:

1. Create new blank notebook
2. Enter code in cell:

import matplotlib.pyplot as plt
plt.figure()
plt.plot([1,2], [1,2])
plt.show()

1. Run cell

@charlieh108 Looks like you might be missing the Jupyter renderers extension. VS Code separates execution from display so different extensions can provide different output renderings. The Jupyter renderers extension is supposed to install with the main Jupyter extension, but it looks like you are missing it. Try installing that, it should provide the right views:

You can see in my second image that it’s using the renderer from that extension.

I don’t know what exactly it does, but there is a vscode setting which may or may not help in this instance:

 "jupyter.themeMatplotlibPlots": true,
