I just realized that in#30426 I accidentally and wrongly removed the dpi arg when generating the png filename (athttps://github.com/matplotlib/matplotlib/pull/30426/files#diff-6a0383194825a76389747fc0b369645f844ddc7fc7f30b300e4413fe40dc4b17L314); I fixed that in this commit as well so this should also be backported to 3.10.6, hence the milestoning (or I can make a separate commit with just that fix, if we want to be really granular...).

Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

1. Checkout backport branch and update it.

git checkout v3.10.xgit pull

2. Cherry pick the first parent branch of the this PR on top of the older branch:

git cherry-pick -x -m1 1c3e0438cb890fe12e91c73b3782cae3b87060a5

3. You will likely have some merge/cherry-pick conflict here, fix them and commit:

git commit -am 'Backport PR #30431: Use pathlib in texmanager.'

4. Push to a named branch:

git push YOURFORK v3.10.x:auto-backport-of-pr-30431-on-v3.10.x

5. Create a PR against branch v3.10.x, I would have named this PR:

"Backport PR#30431 on branch v3.10.x (Use pathlib in texmanager.)"

And apply the correct labels and milestones.

Congratulations — you did some good work! Hopefully your backport PR will be tested by the continuous integration and merged soon!

Remember to remove theStill Needs Manual Backport label once the PR gets merged.

If these instructions are inaccurate, feel free tosuggest an improvement.

Hmm, maybe only backport the fix?

OK, I opened#30434 for the backport with the extra fix. (If you want to first merge the automatic PR and add an extra fix commit on top of that, feel free to do so instead, I don't mind either way.)
