Hello Dmitri, There is no problem if JDestopPane.putClientProperty("JDesktopPane.dragMode", "outline") is not set and the acceleration pipeline is enabled. The 'outline' drag mode was used in our app exactly because there were performance problems with JInternalFrames being dragged around the desktop when no acceleration pipeline is present. So, because we have to support older clients we will start our app with -Dsun.java2d.d3d=false for now.
Thank you and regards, Horia P.S. I will vote for the bug.
