From a subjective view, the test image looks worse. However, I think objectively, it is more correct in that it is doing tight layout, and the z label really is far away.

@scottshambaugh is there some way we can get the labels to not be so far away from the Axes once it is closer to head on?

@QuLogic does this need a rebase for the circleci tests to pass or is it something else?

Yes, needs a rebase.

Can you please add a test that generates the image that you show above?

Right now the label offsets are hardcoded without an rcparam. The labels are drawn here:

In generalaxis3d is not in amazing shape and needs a good bit of attention to clean up and make customizable & robust. But in the meantime for the fix in this PR, I'm reticent to accept a change that messes with tight layout subplots so much.

Opened an issue for controlling the label positions#28606, but I think it's a bit separate from the issue at discussion here.

@QuLogic I don't think the test failing is related to my changes. I re based and force pushed. Let me know if there is anything else to do for this PR :)

I personally don't think this change should be made until there is a way to avoid the super-compressed subplots as seen in the test image, and I don't think that controlling the axis label position like my comment above is a robust way to do so. Not sure what that solution looks like, but would want to see that update made in order for this fix to go in.
