I like that I can watch movies in 24p now but in Netflix it seems like that while Netflix is changing resolutions until it gets up to it's max resolution for the particular movie, it will flash for a second on each resolution change. For example. I start The Do Over (4k HDR movie). At first it may start out at 720P then when it gets up to 1080 it will flash for a brief moment, then when it gets to 1440 it flashes again and when it hits 2160 it flashes again and then since the resolution stays put the flashing stops. Maybe it is a deal with Netflix and maybe it's Roku, not sure. Anyone else seeing this?
Are you sure this is new? I noticed this with one of the 7.x firmware releases when watching a HLS stream. I'm not sure what adaptive streaming method Netflix uses, but the whole idea of adaptive streams is that the device should seamlessly switch from one bitrate to another. A big black flash is hardly seamless. I'd call it a bug that has been around for a while and isn't likely to get fixed if it's not acknowledged by Roku.
^ Just curious, is your Roku on 2.4GHz, 5GHz, or Ethernet when you use remote jack private listening? For some reason I heard audio pops with the 2017 hardware when on 5GHz.
I've had varying results for phone app private listening, depending on the house and router (since audio in this case is routed via the router), and BT vs wired headphones. My own house, iPhone private listening via AirPods don't usually have any issues with audio sync or pops/crackles, on either Wi-Fi band for the phone and Roku. But at another house with similar setup, I often had a small audio delay.
The 30P issue I described earlier only appeared to happen to a few videos I watched while others were just fine at 30P.
