Hey, thanks for the report. The garbled code blocks in chat responses look unusual, so let’s try to debug this.

Please try these steps:

• Fully restart Cursor: close and reopen the app to see if the issue persists
• Check your font settings: open Settings CTRL+,, search for “font family” and change it to a different standard font, since the issue might be font-related
• Test with extensions disabled: run cursor --disable-extensions from the command line to rule out extension conflicts
• Try disabling GPU acceleration: launch with cursor --disable-gpu to check if this is a rendering issue

Also, please share:

• Does this happen with all code blocks or only with specific programming languages?
• A Request ID from the garbled chat (click the three dots in chat > Copy Request ID)
• Which custom themes or extensions you have installed

Let me know what you find.
