title: Pet slept on keyboard, weird colors in IDE
body: <p>Please stop laughing. My cat slept on my keyboard. When I came back I wonder what these colors are:</p>
  <p><a href="https://i.stack.imgur.com/Imm5i.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Imm5i.png" alt="enter image description here" /></a></p>
  <p>I like to get rid of them but I don't know how to remove them.</p>
  <ol>
  <li>Close and reopen of the file does not work.</li>
  <li>Close and reopen of the project does not work.</li>
  </ol>
  <p>Any idea?</p>
