title: Qt WebEngine seems to be initialized
body: <p>When I run my Qt application I get the message </p>
  
  <blockquote>
    <p>Qt WebEngine seems to be initialized from a plugin. Please set
    Qt::AA_ShareOpenGLContexts using QCoreApplication::setAttribute before
    constructing QGuiApplication.</p>
  </blockquote>
  
  <p>The app runs fine regardless of the fact that this is getting dumped to the terminal. I cant seem to find the root cause or really understand what this message is trying to tell me. What is this message saying and how can I fix it?</p>
