セキュリティーサンドボックス侵害エラーが発生していたので、loadするときに、new LoaderContext(true)を挟むようにしました。キャプチャが取れない可能性として、wonderflのキャプチャはstageをBitmapData.drawしているっぽいのですが、drawするときにエラー発生することによりBitmapDataが無効となりキャプチャが生成できなかったのかと思いました。(想像なので、間違っているかもしれません)

僕のはLoaderContext無しにキャプチャ撮れてるのが謎ですね。

確かに。謎ですねｗ

LoaderContextなしにキャプチャ撮れることもあったですよ。
