title: QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-aadithyasb'
body: <p>I am using WSL in Windows 10. I have this warning getting displayed when I run a python file:</p>
  
  <pre><code>QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-aadithyasb'
  </code></pre>
  
  <p>I can understand that the <code>XDG_RUNTIME_DIR</code> environment variable is not set and it is creating its own path <code>/tmp/runtime-aadithyasb</code></p>
  
  <p>I am getting this warning from the moment I installed Xserver for Windows using VcXsrv to open plots when the file is ran. </p>
  
  <p>Wy question is should I add this <code>XDG_RUNTIME_DIR</code> environment variable in windows or is there any method to set a directory under the variable for Ubuntu used under WSL?</p>
