attn. @jklymak who introduced constrained_layout into the gridspec tutorial with #11010. I do however think that at the time this got proposed (i.e. mid April), it did render correctly. So something that changed in between may be responsible.

Some of the plots looks much better on my computer but some of the plots get warnings with both constrained_layout and tight_layout.

I believe that the problem is that some axes collapses under constrained layout ( I believe jklymak added that feature recently) and the new warnings in tight_layout.

I believe the issue where in annotations, see #11801

There are also some other smaller errors in the tutorial that I can fix later.

Well it’s strange that it seems to work locally but is broken at the docs renderer. I’ve also never quite seen axes collapse like that before so it’s a good error to track down. But I can’t look at it for a few days....

It was fixed by #11801

How many more artists have the same problem with get_window_extent and layout managers?

Not sure. We should be sure to add tests for these so they get caught. I’m also a little concerned that now we are playing whack a mole.

The fundamental problem was the change that added all artiss to the ax.get_tightbbox stack. Before it was just axes and their labels. Perhaps that was a mistake, though I think overall it is the right choice.

I guess what’s needed is a test in one or both of the layout managers for every artist that we have and make sure they look good. I guess another issue is the same test(s) should be run interactively maybe just by hand to make sure zooming and figure resize work well. Of course that may not catch all the problems but it’d have caught the annotation bug. I can take a crack at this when I’m back or someOne could do so.

Also on the todo list is improving the documentation on layout managers to make sure set_in_layout is properly explained.

I have started to write some tests that test the interactive behavior.

I don't get pytest to work though...

I don't think there are any action items on this one. Feel free to re-open if I'm mistaken...
