  <p>I am using Ubuntu 18.04, having multiple issues with my Conky setup.</p>
  
  <p><b>First</b>, I use Variety, changing wallpaper application. Now Conky takes the snap of the earliest wallpaper background and uses it till next restart. The same issue with any application also.</p>
  
  <p><b>Second</b>, the dynamic expressions like top processes or data consumption overlap with the previous value i.e. the old value doesn't get cleaned.</p>
  
  <p><b>Third</b>, my Conky texts are leaving black duplicates with a vertical offset, it seems like I'm running two Conky.</p>
  
  <p>Tried purging and reinstalling Conky but no use.</p>
  
  <p>My <b>conky.conf</b></p>
