title: Colored pixels in scrollbar in VS Code
body: <p>I've recently started using VS Code, and I've noticed that there are little colored pixels that show up in the scroll bar like this:</p>
  
  <p><a href="https://i.stack.imgur.com/WFvqI.png" rel="noreferrer"><img src="https://i.stack.imgur.com/WFvqI.png" alt="enter image description here"></a></p>
  
  <p>They seem to indicate something about the source code, but I haven't been able to find the documentation for this. So my questions are as follows:</p>
  
  <ul>
  <li>What is the name of this feature?</li>
  <li>Where is it documented?</li>
  <li>Can this feature be disabled, and if so, how?</li>
  </ul>
  
  <p>EDIT:</p>
  
  <ul>
  <li>After reading <strong>@idleberg</strong>'s answer, I set <code>scm.diffDecorations</code> to <code>"none"</code> and restarted VS Code, reopened files, etc, but the decorations still persist.</li>
  <li>I followed the link in <strong>@Moffen</strong>'s answer and I set <code>"editor.hideCursorInOverviewRuler"</code> to <code>true</code>, but it turns out that controls a different feature. Also, I already had <code>"editor.minimap.enabled"</code> set to <code>false</code>, but the minimap is a different feature from the scrollbar decorations.</li>
  <li>I'm running Version 1.23.1 of VS Code on Ubuntu 18.04.</li>
  </ul>
