Safari Video Playback Turns Black (no video) While Using an Airplay Display
Often while using an airplay display (both another Mac and iPad) on both my M1 Air and Intel iMac, the video playback is invisible, but the audio continues. The specific website this occurs on is Udemy, but I have not tried others. This happens even when the tab is on my main display. This has been happening during Big Sur, and still is on Monterey. Chrome is often what I will switch to, but sometimes that has the same issue.
