Flash Player 9.0 bug

Hello,
Broken animation broken_image_screenshot

Original animation original_image_screenshot

Please tell me why there is this problem?

tests;
Firefox 3 (Beta) - FlashPlayer 8.0 - GOOD
Firefox 3 (Beta) - FlashPlayer 9.0 - BAD
IE 7.0 - FlashPlayer 8.0 - BAD
IE 7.0 - FlashPlayer 9.0 - GOOD

Let me stress the flame ball is very very heavy animation. many overlays and such as the image was imported from Illustrator.
Though, I think importing is not the problem I have checked both programs were set to RGB mode. not sRGB.
I think there is issue perhaps with hardware acceleration or Direct X in the Flash Player?

latest version of Flash Player were used in both browsers: 9,0,115,0 [and also FP 8.0]

Help/opinions would be greatly appreciated,
Mr Ogilvie
