title: Default font sizes in X11 apps under MobaXterm V12
body: <p>I use the free tier of <a href="https://mobaxterm.mobatek.net/" rel="nofollow noreferrer">MobaXterm</a> on Windows to connect to our Centos/RHEL machines and to display X11 apps on the Windows desktop.</p>
  
  <p>In the past I used <strong>MobaXterm V3</strong> and it displayed X11 apps like PyCharm, Eclipse or VS code with appropriate font sizes. Here an sample portion of the PyCharm window under MobaXterm V3:</p>
  
  <p><a href="https://i.stack.imgur.com/PJmQb.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/PJmQb.png" alt="Fonts in Version 3"></a></p>
  
  <p>Now I upgraded to the current <strong>MobaXterm V12</strong> and the fonts for menus and explorer panes are way too big:</p>
  
  <p><a href="https://i.stack.imgur.com/mP9BI.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/mP9BI.png" alt="Fonts in version 12"></a></p>
  
  <p>This happens not only in PyCharm, but in other X11 apps like Eclipse as well - and in apps on different remote machines. So it must have to do with the X server built into MobaXterm.</p>
  
  <p>I compared the output of <code>xset q</code> under both X servers and got the following differences (in the graphics section of the <code>xset</code> output):</p>
  
  <p><strong>MobaXterm V3</strong>
  :   <code>Font Path: /usr/share/fonts/misc,built-ins</code></p>
  
  <p><strong>MobaXterm V12</strong>
  :   <code>Font Path: C:\Users\broleo\AppData\Local\Temp\Mxt121/usr/share/fonts/misc/,built-ins</code></p>
  
  <p>I tried to set the font path in V12 via <code>xset fp</code> to the same as in V3, but it didn't help.</p>
  
  <p>Any idea what to do to make the new MobaXterm V3 display X11 apps with fonts in a similar size as in the old MobaXterm V3?</p>

  <p><em>Note:</em> I know that most apps offer in-app preferences to change font sizes; but often this applies only to editor text, etc and it would need to be done for each app separately. I am rather looking for a tweak to MobaXterm V12 - after all V3 can do it!</p>
