Not sure why you're seeing a difference between AIR and Flex (I would assume they're both using the Flash Player, but I guess AIR uses a special build of the Flash Player to ease security issues). Hopefully someone else can address the AIR issue. Looking at the specific image, though, I would urge you to use a different format for your image data. For high-resolution B&W imagery (grayscale is just masking the reduced resolution) you should either use a specialized renderer (store the image as a ByteArray at either 1-bit or 8-bit depending on the zoom level you want, then render out tiles manually), or if you can get the data in this format from the source, store it as vectors (mxmlc can compile SVG into vector shapes in an SWF, and you can probably find a vector to SVG converter for whatever the originating SVG format is). Troy.
