Diff Viewer not showing correct code

[kroggen (Bernardo Ramos)]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Sometimes the diff viewer displays wrong code on the “old content” (red part)

On the attached image you can see that the code that appears on the normal editor (in red) is not the same code that appears when we click on the left border

The correct is the second: leafPage.ContentSize -= subPageSize
But the editor is showing db.markPageDirty(leafPage)

Steps to Reproduce

I don’t know, it happens sometimes. Not always

I suspect it is after I do accepting of some changes with mouse

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. I noticed that you’re on an older version of Cursor. Could you try updating to the latest version or download it here:
