Some changes don't show up

[Marijn17s]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Whenever the agent makes changes, not all of the changes get tracked. It will report way less in the summary of changes than what it actually did. And when reviewing the file it also doesn’t get highlighted in green as new. Of course with git the problem is less, but between commits, any changes it makes can go under the radar.

This was an issue a few months ago but was fixed for me and seems to be re-introduced. With one of the latest updates

Steps to Reproduce

Let the agent make some changes. Let it add let’s say 20 lines of code.

Expected Behavior

All changes are supposed to be highlighted in either green or red.

Operating System

Windows 10/11

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, this is a known issue. The agent only shows a diff for the first change in a file, and applies the rest without highlighting.

A few users have run into the same thing already: Only some diffs are shown when agent makes changes

The team is aware and the bug is logged. There’s no ETA for a fix yet, but your report helps with prioritization.

As a workaround, you can check the changes with git diff or use the Review button in chat, though I know that’s less convenient.
