JDK 8 b96 64bit, JavaFX 8, Windows 7 64bit, NetBeans 7.3
In JavaFX 8, when using the print API and printing a LineChart offscreen (a copy of a chart that is visible on the app's stage), both chart's axis are blank despite been set to no animation. The chart legend is also missing though empty space is present where it should be visible. See following code that demonstrate the issue.
