You have been subscribed to a public bug:
On Ubuntu 20.04, programming in python and by mixing up left/right and
up/down in matrix operations created an array of size 1x409600 instead
of 2048x200.
When I tried to show the data as an image Ubuntu completely crashes.
Unable to get any form of crash report, only thing I could do was hard
reset my PC.
Here is some code that reproduces the problem:
import cv2
import numpy as np
cv2.imshow("window name", np.zeros((1, 2048*200)))
cv2.waitKey()
