title: logcat in android studio not showing
body: <p>After updating Android Studio to <strong>version 2.2.3</strong>, sometimes(manytimes) it doesn't show logs </p>
  
  <p>Also After re-running application, it doesn't show logs</p>
  
  <p>I have tried <strong>restart button in logcat</strong> but doesn't show effects and have checked all criteria like <code>No Filters, Verbose, selected emulator and application package.</code></p>
  
  <p><strong>Restarting Android Studio works</strong></p>
  
  <p>to be more clear , when i clear logs it doesn't show logs again and every time I have to restart Android Studio</p>
  
  <p>can anyone post a solution to this ?</p>
