title: JavaFX styling broken after upgrade from Java 7
body: <p>After upgrading from Java 7 to Java 8, we are seeing some styling issues in a "legacy" (read: I didn't write it and have no real good experience with JavaFX) application. After multiple attempts to troubleshoot this in Scene Builder (again, no real experience there, please bear with me), I am hoping to get some pointers here. </p>
  
  <p>The image below illustrates the two issues we are seeing with text boxes, buttons, and choice boxes. One, the text box has lost the rounded corner styling (which isn't crucial, but I would like to understand the reason). Two, when hovering over any of the elements, they are covered with a white box, which will eventually disappear after moving the mouse away again and/or clicking somewhere else.</p>

  <p>The application uses several stylesheets and I am not sure which ones are relevant. Any advice or pointers would be greatly appreciated!</p>
