SHAKE for large format images?

Has anyone had experience to process images in large sizes/formats using SHAKE, e.g., >4K, 6K, 8K, even larger? So far, the maximum dimension I can open and process in SHAKE is about 4k x 2.67k, 10m-px images.

I had tried to open images in dimensions of 6k x 4k, SHAKE only shown a corner of the input image. Did I miss some preference condifugration for SHAKE, or it is not designed to do this kind of job?
