When using the 2-step upload (freeze and upload in separate steps) together with different preview and upload sizes the image gets enlarged after webcam.freeze(). This way after freezing you only see the part of the enlarged image that fits into the preview container.
The size should be adjusted on webcam.upload() not on webcam.freeze().
