Does this stop you from using Cursor

No - Cursor works, but with this issue

This lines up with a change in the recent UI: editor and overall font sizing is now controlled by a separate Appearance setting, and after a major version jump it can land on the default size even though your editor.fontSize in settings.json stays exactly as you set it (which is why the value still reads 19 but the text looks smaller).

To get your size back:

  • Open Cursor Settings → Appearance and bump Code Font Size (and UI Font Size, if the whole interface looks small) to your preferred size.

  • You can also use Cmd + / Cmd − to zoom the editor in and out.

To help us pin this down: is it just the editor text that’s smaller, or the whole interface (sidebars, chat, menus)? And once you set the Code Font Size above, does it return to the size you expect?

It is whole. But overall it seems inconsistent. editor one size, thinking another, chat box, answer also have separate sizes.

Sorry, Ican not change the setting, I can not find it

It seems searching stopped to work after 2.x versions.

I tried this. It looks ok, but after a few chat requests it seems zoom out. But editor and agents menu stays zoomed in.

This is too hard to read this small fonts for AI chat.

The different areas rendering at different sizes (editor, thinking, chat input, answer) is a known issue we’re already working on. And the chat text shrinking back after a few requests, while the editor and agents menu stay zoomed, looks like a separate bug on our side - not anything you’re doing wrong.

For the chat being too small to read, there’s a setting that gives a larger size and persists across restarts (unlike the Cmd +/− zoom). Since the search isn’t surfacing it for you, the most reliable way is to edit your settings file directly:

  1. Press Cmd+Shift+P and run Open User Settings (JSON)

  2. Add: "cursor.composer.textSizeScale": 1.3 (1.3 is the largest)

  3. Save

Thank you for the tip. I’ll try it.
