Hi guys,

Sometimes when switching on my Apple TV 4K (tvOS 13.3.1) or when something changes input-wise (e. g. switching from SDR to HDR content) I get some strange grey noise picture which moves. I don't have a direct photo of it but this image from the internet looks approximately like what I'm seeing (but in my case there are also colored bits in it):

The way to get rid of it is to switch to another input on my AVR and back to the Apple TV input. Then everything's back to normal. I also had this problem prior to having an AVR in my setup.

Anyone has any idea if that's some sort of hardware defect or simply a bug? And if it's the latter are there any ways to fix it?

Thanks and best wishes
Chris
