Jerky scrolling in Roon Remote on iPhone 17 with iOS 26.0 [Ticket In]

Describe the issue

Sorry if this has already been discussed somewhere. I've found old threads, but no new replies on this topic.

On the iPhone 17, IOS 26.0 scrolling in Roon Remote is very jerky.

I think it's especially noticeable now to me because of the 120Hz proMotion display on iPhone 17. Roon Remote (1554) is the only app that behaves this way.

Is there any prospect of a solution?

Hi @Bolus ,

Thanks for your report. Can you please confirm where the issue occurs, it is on all pages in Roon or one in specific? Does one page reproduce the issue more obviously? If you go to your iPhone Settings → Accessibility → Motion → Limit Frame Rate, does that temporarily alleviate the issue?

[Bolus]

Thanks for your reply. Yes it does alleviate the issue, but even then I wouldn’t call it smooth.

Jerky scrolling has been an issue on 120hz iDevice displays since they were first released. There are numerous existing threads discussing the issue.

Don’t expect it to be addressed soon or ever.

Good day @Bolus !

Thanks for sharing your report.

We were able to reproduce this problem from Support side.

We have therefore open an internal ticket to R&D and will proceed further with this.

Have a nice day!

Regards.

There must have been a ticket since at least last year when „implementing a fix“ for 120 Hz scrolling was already mentioned:

Pro-Series iOS Phones Not Locking to 120FPS Refresh Rate [Ticket In: Affecting Pro-Series iPhones]

Hi everyone, This ticket has been moved and retitled to address the specific fix we’re implementing to allow Roon to operate at the higher frame rate on ProMotion-equipped iOS phones (Pro Series). To report a support issue with iOS more generally, please create a new topic thread. Scrolling issues contain two components: the hand gesture, and the response within the app. Without both pieces of information, we’re often relegated to a blind fix. The more precise the report, the more actionable. …

Hi everyone,

Our previous effort addressed edge cases and added logging, but we have yet to fully resolve the issue of 120FPS-capable iOS phones not locking to the optimal frame rate.

You’ll likely notice that if you take a screen recording and then scroll within Roon, it’s much smoother. The phone is locking to 120FPS as expected while recording. The goal is, of course, for Roon to do this automatically when the higher frame rate is available from the OS.

There’s a ticket in the pipeline to implement a standard fix for this, but it’s not slated for release in the upcoming Roon update. As soon as the ticket has progressed through the pipeline, we’ll make an announcement here. We can consider this a new tracking thread since we have a new ticket.

Thank you for your patience.
