Description
Expected behaviour
Use opencv to do picture output, hope it can be stable output for a long time
Actual behaviour
I am now using opencv to output images, and I find that after running for some days, the output images are not very stable. On a same screen, the previous picture shows a part, the last picture shows a part.I use code cv.imshow cv.waitKey
Steps to reproduce
- cv.imshow cv.waitKey
- ubuntu20
- e.g. x86
- opencv-python 4.x

Research direction
Start by reproducing the long-running behavior with cv.imshow and cv.waitKey on Ubuntu 20, x86, using opencv-python 4.x. Compare successive output images on the same screen and document whether parts of previous frames remain visible. Done means the output remains stable over multiple days, or the issue is narrowed to a reproducible environment-specific failure.
