title: Different images from Webcam with OpenCV 4.20 builds (MSVC 2019 (good image) and MinGW(weird image))
body: <p>I was using OpenCV 4.2.0 on Microsoft Studio which I downloaded the pre compiled version from the official repository, it was working fine. Then I decided to move to MinGW and compiled the source code of the same version. Everything seemed to work but when I tested the video capture on MinGW, I am getting this weird effect which don't happen with my Microsoft Studio. Look at the difference, the picture on the left is from MinGW and the right one is MSCV2019, with the same camera parameters and taken at the same time.</p>

  <p>Anything I can rid of this undesired effect? I tested the input image on other webcam softwares and it doesn't seen to happen.</p>
