i tried lost in space in Netflix s1 between the 37 abd 38th minute mark, and i definitely saw some kind of slowdown/stuttering issues, and I have seen this effect in altered carbon too.

Are my eyes deceiving me or are you experiencing the same?

Btw I can’ t enable hdr in the YouTube app, tried a dozen 4K hdr clips, but there is no option to turn it on anywhere, just 1080p60, no hdr. Any tips?

Also having the same problem on my XS max. No option for YouTube HDR.

Is anyone with a regular sized X/XS having the same issue or is it limited to the max?

Im experiencing the same. No HDR option in the YouTube app.
 
It could be a problem because of the new res of the XS max, and YouTube not recognizing it.
But perhaps there is someone with a regular sized XS (same red as the x) that could test this?

But no one having judder issues with Netflix , slight stuttering and jerkiness in Dolby vision hdr content when watching full screen?
I have, especially when a lot is going on onscreen, and there is plenty of bandwidth, so that can’ t be the problem.

I have an XS max and Netflix (UK).

Tell me what show you’re having issues with and I’ll check it out on my XS max to see if I get the same issues as you.

Lost in space, especially episode 1 with the snow and mountains (about 40 mins)
 
I have experienced exactly the same kind of problem micro-stuttering issues on the avengers infinity bought on iTunes. I have an iPhone XS Max also.
Hardware or software problem ? I don't know
 
There was quite a lot of stuttering on Netflix Ozark season 2 episode 5 I watched today in full screen. Definitely an issue there.

I’m having the same issues on an XS with YouTube. Issue doesn’t exist on my old X and I did a side by side comparison with the same video.

As the above person said, it will never be available unless apple accepts vp9 or google accepts h265 for video playback

This doesn’t make since I was literally just watching an HDR video on YouTube per the playback quality on my X. Right next to it I had the XS playing the same video and the playback settings didn’t show HDR. Even the video were clearly different in their color range. Im not talking about getting 4K playback just getting the 1080p HDR setting on my XS like it is on my X.

Well, I’m having the same issue on my XS Max on HDR downloaded content from iTunes. The Post is nigh unwatchable because of it.

It’s either a bug in OS12 or a hardware problem. I’ve tried everything to solve it to no avail. It does it when a movie is downloaded too. Considering returning it.

Same issue as you, some small amounts of stutter around that scene. Looks like other people are also having the same issue.

I hope it’s something that can be fixed with a software update :/

I think it would be helpful to submit feedback to apple about it so we can hopefully get a fix soon.

But does this stuttering of movie playback in iTunes and Netflix also appear on the regular xs?
Could someone try that out?
 
Ok thanks,
To me it seems the issues occur especially on Dolby vision /hdr content and with big panning shots, smoke/mist effects and scenes shot with bokeh effects.

Perhaps someone with a xs max has 12.1 beta installed? Are you experiencing the same problems ?
