Tkinter GUI tested on Linux shows corrupted images on Windows10

I wrote a GUI using tkinter on Linux, which just loads and displays images from numpy arrays, which is converted into a image using PIL, and then to a PhotoImage. This is loaded into a Canvas. Everything works perfect in Linux, Python2.7:
import Tkinter as tk
import numpy as np
from PIL import Image, ImageTk
# array is a 2D numpy array.
image = Image.fromarray(array)
image = image.resize((width, height), Image.ANTIALIAS)
# Until this point, I can display the correct image on the IPython console using imshow()
image = ImageTk.PhotoImage(master=root, image=image)
canvas.create_image(0,0, anchor='nw', image=image)
Now when testing this GUI on Windows10, everything works fine, but the image loaded looks corrupted. The original image was a normal-looking gray-scaled MRI. The displayed image on Windows looks like this:
No matter what image I load, they all look like weird vertical lines. No recognizable shapes or anything.
Does anybody recognize this type of corruption? The image looks fine after converting from array and resizing. But after using ImageTk.PhotoImage everything seems to go wrong.

Please provide some data that can be used to create a 2D numpy array to allow folks to recreate the problem.

Try using a Label instead of a Canvas. Do you still get the same result?

@martineau But not even I can recreate the problem. This seems to be a system dependencies issue. I am asking for help in recognizing the image corruption and possible links to python libraries

@Novel Everything else in the program works fine. Including other labels, widgets, buttons.. The one and only thing not working is the image display

I mean put the image in a Label instead of a Canvas. I want to know if it's the image or the Canvas that causing the issue.
