SWF playback issue in full screen on Vista

programming flash
1

Does anyone have any info or experience with resolving full screen / hardware acceleration issues on Windows Vista?

I have a Flash piece that can toggle to full screen using the “ScreenSourceRect” parameter.

Things run fine when in full screen mode on Mac 10.4, 10.5 and Windows XP SP3.

But the animation slows to a crawl at certain points when in full screen on Vista (both 32 and 64 bit).

However, it is only the SWF file that runs poorly on Vista. When exported as a projector file, the animation plays normally.

I have tested this on two separate Vista machines with the same results.

I also noticed that when I un-check hardware acceleration from the Flash player settings panel, then the SWF file on Vista does play faster (albeit more pixelated due to the lack of hardware scaling).

Has anyone heard of or experienced this play back issue with Vista, full screen mode, and hardware acceleration enabled?

Some more details about my setup:

I am using AS2.

Files were exported from Flash CS3 as Flash Player 9.

I also tried exporting from Vista directly using Flash CS4, as both Flash player 9 and 10.

The code I am using to enter full screen is as follows:

introScreen.fullScreenBut.onRelease = function(){
        var scalingRect:Rectangle = new Rectangle(0, 0, 1000, 700);
        Stage["fullScreenSourceRect"] = scalingRect;
        Stage.displayState = "fullScreen"
        play()}
}
