I have noticed when I use either Microsoft Edge or Safari. watching YouTube that occasionally the video will have a red shift to it. If I move my mouse, the shift goes away and the video is normal. I have MacOs Catalina running on either a MacBook Pro or MacMini.Although if I am using MacOs High SIerra, the shift isn't present. Therefore, since I have a Windows partition set up, I generally stay in Windows using Microsoft Edge with no red shift to the video. Any ideas?
