Insertshape function produces odd results for very large images?

So I have been using the Insertshape function for several images of roughly 5000x5000x3 size and inserting >100 polygon shapes with no issue.
However when I attempted the same thing with a rather large trucolor images (30k x 30k x 3), it seemed to introduce various bugs. 1. All the shapes inserted properly but Half of the original image was deleted. So there was just polygons on a black canvas for half the image. 2. The color data also seemed to be delete, switching from RBG to just red.
Matlab did not produce an error in the code when I ran it so its not really clear whats happening. I was just wondering if this is a common issue with insertshape for very large images. (The image takes up a few gigabytes of memory).
