[Bug]: EPS savefig messed up by 'figure.autolayout' rcParam on 3.5.0 #21930
Description
Bug summary
Setting 'figure.autolayout' to 'True' removes most of the EPS savefig.
Code for reproduction
import matplotlib.pyplot as plt
plt.rcParams['figure.autolayout'] = 'True'
plt.plot([1, 2, 3], [1, 2, 3], 'o-')
plt.title(r'$\sum_{i=0}^{\infty} x_i$ just a test')
plt.savefig('test2.eps', format='eps')Actual outcome
Actual image after being exported from gimp (300dpi)
This is the EPS file:

Expected outcome
Expect the image in ".eps" file like this.
This is the EPS file:

Additional information
I found this bug by an accident while using a custom ".mplstyle" on Matplotlib 3.5.0
Seems like this rcParam ['figure.autolayout'] = 'True' destroys about 2/3 of the eps file.
plt.tightlayout() seem to not affect the result, the bug happens only with this rcParam on the latest matplotlib version.

plt.savefig('test2.eps', format='eps')This is the code for the expected outcome.

I can confirm this, but I don't understand it. If you instead do
it works fine.
If you use the rcParam and save as PDF it works fine. So I'm not sure why the ps backend is doing something different.

Same behaviour with plt.rcParams['figure.constrained_layout.use'] = True.

Still not fixed in 3.5.1

someone will have to dig into it before it gets fixed.

I'm not sure how you got this to work, I see no appreciable difference in the file between the rcParam vs the parameter (i.e., both are broken).

Oh good, I must have been mixing up files somehow. Glad that it is consistent between the ways to set tight_layout...

I've just tested it out and...
gives a broken result like with the rcParam.
But
does not. 🤔

Same here with version 3.5.1 in archlinux.
And some lines are lost at the end of broken eps, like gsave, grestore things:
