у флэша есть шесть состояний свойства _quality - autohigh,autolow, high, medium, low, best
Так вот, autohigh автоматом в зависимости от свободных ресурсов выставляет по убывающей свойства high medium low, а при значении best происходит сглаживание растра, чего не происходит при значении high, может быть загвоздка в этом.

Template variable: $QU

Description
(Optional) Specifies the level of anti-aliasing to be used when your application plays. Because anti-aliasing requires a faster processor to smooth each frame of the SWF file before it is rendered on the viewer’s screen, select one of the following values based on whether your priority is speed or appearance:

Low favors playback speed over appearance and never uses anti-aliasing.

Autolow emphasizes speed at first but improves appearance whenever possible. Playback begins with anti-aliasing turned off. If Flash Player detects that the processor can handle it, anti-aliasing is turned on.

Autohigh emphasizes playback speed and appearance equally at first but sacrifices appearance for playback speed if necessary. Playback begins with anti-aliasing turned on. If the frame rate drops below the specified frame rate, anti-aliasing is turned off to improve playback speed. Use this setting to emulate the Antialias command in Flash (View > Preview Mode > Antialias).

Medium applies some anti-aliasing and does not smooth bitmaps. It produces a better quality than the Low setting but a lower quality than the High setting.

High favors appearance over playback speed and always applies anti-aliasing. If the SWF file does not contain animation, bitmaps are smoothed; if the SWF file has animation, bitmaps are not smoothed.

Best provides the best display quality and does not consider playback speed. All output is anti-aliased, and all bitmaps are smoothed.

The default value for quality is high if this attribute is omitted.
