<div>
<pre>Decoding multiple frames from the same image is not thread-safe. Since the next frame may not be ready at the time BitmapImage::draw() is called, the current frame has to be drawn. If the current frame is not available, drawing the current frame will invoke the image decoding from the drawing commit thread. This may lead to a crash when two threads update the image decoded frames data at the same time.</pre>
