Glass / Agent chat: “Text size = Small” saved but not applied (regression vs 3.11)

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Environment

  • Cursor 3.22 (upgraded from 3.11.19, where agent chat text felt correct at Small)
  • Linux (Ubuntu, DISPLAY=:0)
  • Layout: Agent / Glass (unifiedAgent)
  • Plan: Pro

Setting

  • Cursor Settings → Agents → Text size = Small
  • Confirmed in ~/.config/Cursor/User/settings.json:
    • "cursor.composer.textSizeScale": 0.85

Actual

  • Chat body text stays large despite Small and 0.85 in settings.
  • Reload window / toggling Text size does not change transcript typography.

Impact

  • Harder to read long agent threads; forces workarounds (e.g. global window.zoomLevel) that shrink the entire IDE.

Ask

  • Restore 3.11 behavior: wire Agents → Text size to Glass agent message rendering, or document if Small is deprecated in Glass.

see the attachment where I compare chats with 3.11 (first) and 3.22 versions (second).

Steps to Reproduce

  1. Open Cursor Settings → Agents.
  2. Set Text size to Small.
  3. Open Agent chat; compare message body text to 3.11 with the same setting (or check cursor.composer.textSizeScale is 0.85).
  4. Text size in the main agent transcript does not shrink.

Expected Behavior

  • Agent transcript (user + assistant markdown) renders noticeably smaller when Text size = Small, as in 3.11.

Additional Information

  • cursor.composer.textSizeScale documents scale relative to ~12px base.
  • In 3.22 Glass build, the Agents UI appears to write this setting (chat_text_size analytics / config update), but the main Glass agent transcript does not seem to consume it for markdown rendering (setting persists; UI unchanged).

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey @Igor_Tomalski, thanks for the report and the side-by-side screenshot.

This is a known issue we’re already tracking, and I’ve added your report to it. The Agents > Text Size value still saves to settings.json, but the agent chat transcript currently doesn’t apply it, so the text stays at the default size.

For now the only workaround is zooming the whole window (Ctrl + = / Ctrl + -, or “window.zoomLevel” in settings.json). I know that’s not ideal since it also shrinks the editor and the rest of the UI. We’ll update this thread once there’s a fix.
