title: Can I do anything about "repaints on scroll" warning in Chrome for "overflow:scroll" div
body: <p>In Chrome DevTools, under Rendering, there's an option to "Show potential scroll bottlenecks".</p>
  
  <p>When I enabled this, some <code>div</code> elements I have on the screen with <code>overflow:scroll</code> show a flag at the top saying "repaints on scroll."</p>
  
  <p>I can't find a lot of documentation on this feature, and I don't know whether it's something I can actually fix or improve upon, or just a statement of fact - the divs have content, and they do indeed scroll.</p>
