I don’t know if it has been resolved. We gave up a week ago and began using a web version of the font directly from the designer. You should be able to reproduce directly on fonts.adobe.com unless you have actively corrected the issue on your end.

Thank you for submitting this feedback. Is this issue still persisting? Which applications and interfaces are you seeing this issue in?

Following up to note that Gibson is also off, only 1–2 px, but still off. This change likely occurred at some point in the last 7–10 days. For Gibson, the additional space is above the line instead of below.

Font randomly stopped respecting line height. This only happens for Aktiv Grotesk. Temporary solution is to set line height explicitly and change display to inline-block.

Multiple instances of other people experiencing this issue going back five years:

No known reason for the font to begin rendering incorrectly.

New instance of the same previously reported issue:

Thanks for the update and resolution, much appreciated.

Our team has updated Aktiv Grotesk vertical metrics to the foundry specifications (available as of 29 Feb).

Your web project(s) will need to be updated to get the new font version. Instructions on that:

Let us know if run into any other questions on it!

This is the response received after reaching out to the font foundry/creator:

What you've described is an issue we are aware of; a general summary of the problem is that Adobe is changing the vertical metrics of the fonts we submit to them. We are assuming that this is something which happens automatically on their system during the submission process.

Our team are currently in talks with Adobe on fixing this and hope to have it resolved very soon, though the ball is very much in Adobe's court with this, so I am unable to provide a time estimate; you will need to get back in touch with Adobe.

It's also worth noting that Adobe do not update our font library as promptly as we do should an issue be discovered or a new script supported.
