title: Qt KDE theme stylesheet
body: <p>I am using KDE theme Breeze Dark. Since all my Qt applications have changed its colors. Earlier my applications wasn't altered by KDE themes but now I am receiving message: "kf5.kiconthemes: "Theme tree: (Breeze)". I was changing background colors in my apps using stylesheets. Now due to changed fonts colors it is impossible to read (white text on very bright background). What is more I am not able to get default background color.</p>
  
  <p>qDebug() &lt;&lt; qApp->styleSheet(); gives me empty string.</p>
  
  <p>How to get background color? I would like to use it setting my own backgrounds (showing priority of a task, little more reddish background and so on).</p>
