Description

Does this issue occur when all extensions are disabled?: Yes

  • VS Code Version: 1.106.0-insider
  • OS Version: Windows

Steps to Reproduce:

  1. Open a file removals/additions right next to each other.
  2. Open settings.json and add the following lines:
    "diffEditor.insertedTextBorder": "#bcdbc9",
    "diffEditor.removedTextBorder": "#ff07076c",
  1. Note how the border behaves differently between addition and deletion, on deletion, it shifts the line down and right (for the border), does not happen in addition.

The bug is in the diff editor's border rendering for removed text. The border shifts lines down and right. Look at the diff editor CSS classes related to `removedTextBorder` in the VS Code source, likely in `src/vs/editor/contrib/diffEditor/` directory. Compare with `insertedTextBorder` to find the difference. The issue has an assignee, so check if there is an associated PR or comment before starting.
