Ugly flashing when opening a css-styled stage

FYI: the JDK Mac OS X Port Project has been completed long time ago, so 
currently the macosx-port-dev@ mailing list isn't appropriate for almost 
anything.

Please report JavaFX bugs at: https://javafx-jira.kenai.com/

AWT/Swing/JDK bugs can be reported at: 
http://bugreport.java.com/bugreport/ (or http://bugs.sun.com/ )

If you wish to participate in the development of the technologies (e.g. 
you want to contribute a patch for JavaFX or JDK platform), then you're 
welcome to post your suggestions on the appropriate development mailing 
lists (openjfx-dev@, awt-dev@, swing-dev@, etc.)

best regards,
