White Video Flickering in Full Screen Mode (Apple TV or Netflix)

Hi, when watching a video in full screen mode white random flickering occurs. It happens with both Apple TV, Netflix and other services. It only happens in full screen mode.

I have already tried:

• Restarting the MacBook
• Reseting NVRAM/PRAM and SMC
• Disabling graphics switching: my MacBook only has the builtin graphics card and so not an option
• Disabling dark mode

My system is a MacBook Pro Early 2015 model and running MacOs Monterey v12.6.2.

Thanks for you help in advance,

Josh
