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.

Contributor guide

Research direction
Investigate the CSS border styling for the removedTextBorder class in the diff editor. Check how the border is applied and if it causes layout shift due to box sizing or border width affecting the element's position. Use browser DevTools to inspect the diff editor DOM and trace the CSS rules.
