I have a Macbook Pro 15 in, 2019 2.6 GHz 6-Core Intel Core i7. It's running macOS Catalina 10.15.1
My issue is: when I run Quicktime full screen, the screen starts to flicker. It does not happen every second but in undefined intervals.
What have I done: Initially, I was running Mojave, so I updated to Catalina. I also checked the updates for Quicktime Player to see if that works but seems like it doesn't.
Others: I have tried running YouTube in full screen too but that seems to work fine. So, I believe the issue is with Quicktime.
How do I resolve it?
Your help would be highly appreciated 🙂
