Expected behavior:

import cv2

cv2.namedWindow("Test GUI",cv2.WINDOW_NORMAL|cv2.WINDOW_OPENGL)
img=cv2.imread("test.png")
img=cv2.cuda_GpuMat(img)
cv2.imshow("Test GUI", img)
cv2.waitKey(0)
cv2.destroyAllWindows()

The above code can run normally in a real environment, but cannot run in WSL2! How to solve it or what alternative solutions are available to prevent the download of memory from the GPU to the CPU from increasing program time!

Actual behavior:

import cv2

cv2.namedWindow("Test GUI",cv2.WINDOW_NORMAL|cv2.WINDOW_OPENGL)
img=cv2.imread("test.png")
img=cv2.cuda_GpuMat(img)
cv2.imshow("Test GUI", img)
cv2.waitKey(0)
cv2.destroyAllWindows()

Glxgears is running normally!

If the GPU's GpuMat is downloaded to the CPU's Mat, it can be displayed normally!
