End Of The World Flash In POTC At World's End, Did Anyone See A Huge Fly Silhouette Flash On The Screen, Almost Like A Hidden Frame?

In POTC At World's End, did anyone see a huge fly silhouette flash on the screen, almost like a hidden frame? - end of the world flash

Pirates of the Caribbean: At World's End, I saw a huge black silhouette of a fly (at least 5 feet high) flash on the left side of the screen for a second, as a one-shot - frameworks, such as hidden frames in Fight Club. Does anyone else see? It was three quarters of the way through the film in a scene in which everything we see a great expanse of blue sky and sea (sorry, I can not over-specific, as it happened). It was certainly not a fly on the roll of film or something, so it was a completely black silhouette, almost like a bow tie clip art is real (the different colors and have more defined). Please let me know if you've seen!
