Bug summary

When trying to display a a plot in full screen mode using pyplot, part of the figure is off the screen. The settings of the plot are definitely correct, since manually resizing the window fixes the issue.

Code for reproduction

import matplotlib.pyplot as plt

fig, ax = plt.subplots()
ax.plot([0],[0])

# plt.subplots_adjust(left=0.004, right=0.565, bottom=0.442, top=0.98) # <-- this line fixes it (on my screen)

# the culprit
plt.get_current_fig_manager().window.state('zoomed') # windowed full screen
# plt.get_current_fig_manager().full_screen_toggle() # non-windowed full screen | this also breaks, but this time there is no x to close the window

plt.show()

Actual outcome

Expected outcome

Additional information

The issue can be manually fixed by calling plt.subplots_adjust with some predetermined values, obtained by playing around with the GUI sliders. But this is clearly not the intended way.

If plt.get_current_fig_manager().window.state('zoomed') is used, manually resizing the window (snapping it out and back into full screen) fixes the issue.
If plt.get_current_fig_manager().full_screen_toggle() is used, the window can not be dragged (since its really in full screen mode), but it can not even be closed, because there is no x in the top right corner (I don't know if that is intentional or not).

EDIT: The error only occurs, when the Windows GUI scale (under Settings > System > Display > Scale and layout) is not set to 100%.
