Udemy videos are black on dual monitoring

Hey guys,

I recently bought a MacBook Pro and I am learning stuff from Udemy. I open the video on my second monitor so I do exact things on my laptop screen while I watching the lesson on the other one.

I had no problem even on yesterday! (13.12.22).

Today I sit for studying and saw that Udemy videos black screen and only audio. I saw that new update for Big Sur and Safari came so I thought "Oh it is because of that probably" but even after the update nothing got fixed.

So I searched online and found out that this is the issue about some copyright stuff. Which is interestingly doesn't happen on Netflix or Disney. Only on Udemy??!

If you change your hardware acceleration on Chrome, you may be able to do dual monitoring with the video. But nothing for Safari.

While I searched my problem online I found out that this is an ongoing issue on Mac-Udemy and a lot of people are suffering. Nobody even tried to fixed this for months and months and now it happened to me.

I recently become a part of the MacBook world and it is kinda disappointing to see something like that. People are writing stuff and apple support is only "Yo! Write to Udemy it is not our problem"

Dude this is 100% MAC AND SAFARI problem obviously.

Also it is funny that it didn't happened to me before the update.
