Mac OS X Lion and Java7 + JavaFX2.1 performance issues

Question

Currently I'm using the JavaFX 2.1 GA Build with Mac OS X Lion (10.7.3) on my MacBook Pro (2.33 GHz Intel Core 2 Duo, 4GB 667 MHz DDR2 SDRAM, ATI Radeon X1600 256 MB) an run into some performance and ui problems. The overall rendering framerate is arround ~30fps (which is normally 60fps on my desktop computer) and if I try to resize the main window the window starts to flicker and I get the following exception:
Glass detected outstanding Java exception at -[GlassRunnable run]:src/com/sun/mat/ui/GlassApplication.m:163
Exception in thread "AWT-AppKit" java.lang.NullPointerException
at com.sun.glass.ui.mac.MacView._uploadPixels(MacView.java:72)
at com.sun.glass.ui.View.uploadPixels(View.java:706)
at com.sun.prism.j2d.J2DPresentable$Glass$1.run(J2DPresentable.java:99)So, how can I avoid the flickering and the performance drop? Any suggestions?

2.1 system requirements =>

For JavaFX applications to take advantage of the new hardware acceleration pipeline provided by JavaFX, your system must feature one of a wide range of GPUs currently available in the market. Table 1 lists the graphics cards that have been tested with JavaFX. If your system does not support hardware acceleration, then JavaFX uses the Java2D software pipeline.
For Mac OS X, the following standard Apple hardware graphics chips provide the required support:
- Intel HD Graphics 3000 processor with 288MB of DDR3 SDRAM shared with main memory
- AMD Radeon HD 6630M graphics processor with 256MB of GDDR5 memoryYour graphics card is not on that list, so JavaFX is falling back to a software pipeline, which does not work that well for you. You may not be able to resolve some performance issues when using a software pipline. You can log an issue at http://javafx-jira.kenai.com to request the NullPointerException be fixed - as that should not occur in any case and is a bug.
