Sorry for not being so clear before. I’m not using a zoom add-on. I was referring to the feature that comes with the new Anki version. Also, changing the overall interface size wouldn’t solve this particular issue since only some specific icons and pieces of text are disproportionally large.
Actually, the text size in the fields is not a problem. In the images above, I tried to show that the text in the Templates screen takes much more space in version 2.1.50 (1st image) than in the previous one (2nd image). I believe the card styling in the second image is a lot easier to read (even when using a more compact code formatting as I did).
Hopefully, I could clarify things.
Thank you for considering those changes.
