title: How to increase screen font size in lyx 2.3? (lyx 2.2.3 works)
body: <p>I want to increase the screen font size in lyx 2.3 because it is extremely small.</p>
  
  <p>However, when I use ctrl+mouse, the font size of some words change, but not the whole document. Please see attached 2.3_before and 2.3_after.<a href="https://i.stack.imgur.com/jNNn6.png" rel="nofollow noreferrer">2.3_before</a><br>
   <a href="https://i.stack.imgur.com/CIy1i.png" rel="nofollow noreferrer">2.3_after</a></p>
  
  <p>When I turn back to lyx 2.2.3, there is no such problem. Please see attached 2.2.3_before and 2.2.3_after.<a href="https://i.stack.imgur.com/x326Z.png" rel="nofollow noreferrer">2.2.3_before</a><br>

  <p>It is super annoying and I don't know how to solve it. I don't want to use lyx but I have to.... </p>
  
  <p>Any help would be appreciated. Thank you very much!</p>
