Bug report

Bug summary

When run interactively from python console or ipython, the size of the ui (buttons) and figure dpi are normal. However, if the same code is placed in a script and called from console or IDE (vscode), the zoom level is much larger.

I suspect it is related to my screen resolution (2160x1440)

Code for reproduction

Just first create a script and paste the following code inside, then run the code line by line in ipython.

import numpy as np
import matplotlib.pyplot as plt

fig, axes = plt.subplots(1, 2)

n = np.arange(100)
axes[0].plot(n, np.sin(n))

axes[1].plot(n, np.tanh(n))

plt.show()

Actual outcome

If your screen has high dpi, you should see two figures with different zoom levels.

Expected outcome
The zoom level should be the same.
