Interesting fact. If the white flashes happen and those of you are running through an AVR, please note if the AVR is trying to resync the handshake. I just experienced something similar and my AVR was also flashing. Not sure if I was seeing same thing but audio was also affected. I wouldn't be surprised if it's a HDCP 2.2 issue. Just my 2 cents.
