Nope, haven’t changed anything.
import PIL.Image as Image
import matplotlib.pyplot as plt

with Image.open("seed10.png") as im:
    plt.imshow(im)

This gives me the same image. With seed10.png being the correct image above.

Also tried grabbing the screencapture above as .jpeg, gives me the same result.
This is with matplotlib 3.4.2 and pillow 8.4.0.
But i guess this isn’t really a pytorch issue anymore.
