Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
On Windows (Cursor 2.5.17), the inline diff with red/green highlighting and Keep/Undo buttons only appears when the AI edit contains removals only. If the edit has additions only, or both additions and removals, no diff UI is shown — no highlighting, no Keep/Undo buttons. The diff UI appears only for purely deletion edits.
Began occuring mid-use on 2.5.20, then tried to fix by changing user settings adding ( “cursor.inlineDiff.mode” : “inline” ) to settings.json. Attemped Developer: Reload Window command. Nothing
Uninstalled, deleted all data/info settings for cursor system wide and reinstalled 2.5.17 fresh, same problem still occuring.
Environment: Windows, Cursor 2.5.17
Steps to Reproduce
Any agent edit request has the UI bug. Red/Green diff and keep/undo are helpful to workflow / review.
Operating System
Windows 10/11
Version Information
Cursor 2.5.17 / began in Cursor 2.5.20 on Windows 11 25H2 (Build 26200.7840)
