This looks like a bug in JavaFX when applying the lighting effect. I was
able to reproduce the dirty rect rendering on my system. The bug went
away if I commented out the following line:
iview.setEffect(lighting);
Can you please file a JIRA so that we will fix it?
Thanks,

I’m getting a rendering bug with a simple rotating path in front of an

Looks like some sort of dirty rect problem. Am I doing something wrong or
should I file a bug?
The code is below. If anyone has an idea for a quick work around, let me know.
