### Where does the bug appear (feature/product)? Cursor IDE ### Describe the Bug After a recent Cursor update, all Chinese text in the Agent window looks bold, while the same Chinese characters in the editor stay at normal Regular weight. English in the Agent window only looks slightly heavier (Medium). Chinese looks distinctly bold. This is not a theme “bold keywords” issue — the entire Agent transcript, including plain prose, is thick. This started after upgrading Cursor. I did not change editor.fontWeight or install a new CJK font. Likely cause: Agent/chat uses a separate UI font stack (Cursor Gothic / Inter / SF Pro / system-ui) at font-weight 500. Those faces have no CJK glyphs, so Chinese falls back to PingFang SC Medium on macOS. The editor uses Regular (400), so its CJK fallback is PingFang SC Regular and looks normal. editor.fontFamily / editor.fontWeight do not affect Agent chat. This matches official guidance that editor font settings do not apply to chat. ### Steps to Reproduce 1. On macOS, open Cursor 3.19.x with a light theme (I use Visual Studio Light). 2. Open any source file and type Chinese, e.g. 字体加粗测试. Editor weight looks normal. 3. Open the Agent panel and send the same Chinese sentence, or ask the agent to reply in Chinese. 4. Compare the two side by side. ### Expected Behavior Chinese in Agent chat should render at Regular weight, same as the editor (PingFang SC Regular / weight 400), not Medium/Bold. There should either: - use font-weight: 400 for Agent prose, or - include an explicit CJK fallback such as “PingFang SC” at Regular, or - expose UI / chat font-weight (not just Text Size / UI Font Family). ### Operating System MacOS ### Version Information Version: 3.19.7 VSCode Version: 1.128.0 Commit: 90de2327392570a5f5f625c656c6749d228e6430 Date: 2026-09-02T23:03:07.739Z OS: Darwin arm64 24.6.0 macOS 15.6.1 (24G90), Apple M3 Max ### Additional Information Theme: Visual Studio Light editor.fontSize: 13 No custom editor.fontFamily / editor.fontWeight (defaults) Editor Chinese: normal Agent Chinese: all bold Related: Agent and editor already use different font paths - [How Do I Install Times New Roman Font In Cursor](https://forum.cursor.com/t/how-do-i-install-times-new-roman-font-in-cursor/167051) - [Agent Window Changes code does not use correct font](https://forum.cursor.com/t/agent-window-changes-code-does-not-use-correct-font/134539) I could not find an existing report for this CJK Medium-fallback case. Workaround I have not found in official settings: Classic IDE layout has no chat font-weight control. Cursor Settings → Appearance → Typography → UI Font Family (Agents window layout) may help if I switch the UI font to PingFang SC, but that still will not fix Medium vs Regular if chat stays at weight 500. ### Does this stop you from using Cursor No - Cursor works, but with this issue # screenshot follow as ![image](https://us1.discourse-cdn.com/cursor1/original/3X/8/0/80e9954d207212af002481626b876f3e82c392d0.png) ---

Hey @cscs This isn’t intended behavior, and it’s nothing you misconfigured. We’ve let the team know and it’s an issue we’re tracking. Quick fix to get Chinese back to Regular right now: Cursor Settings → Appearance → Typography → UI Font Family, and set it to `-apple-system`. The extra weight only kicks in while you’re on the default UI font, so setting a custom one drops it back to Regular (and `-apple-system` keeps the same look otherwise). Turning off Font Smoothing in that same section works too. Let me know if that sorts it out! ---

None of the font family options seems to correspond to “Apply System.” ![image](https://us1.discourse-cdn.com/cursor1/original/3X/d/1/d1c057e31d24f5afb97c07c4222b8267ee9b8a30.png) And The reported issue occurs when I set the font family to “System Font.” ---

@mohitjain can you review this issue again ? And is there any fix progress ?
