Off topic: I wish someone would do this kind of analysis to determine why Microsoft Teams helper process is always at 50-70% CPU load on my M-Based MacBook Pro.
My laptop is warm/hot to touch as a result of it.

#12Can't reproduce this on macOS Ventura 13.6 on a Mac Studio.
Me neither (both Monterey and Ventura sit on 0%). Maybe it depends on the items you have in there? I don't think I've ever made any changes.

13.5.2 on Mac Studio and I def see it at 1,0 to 1,5 when not using it. Will update this mac later.
13.6 on my M2 MacBook air: 0,8 tot 1,1 when idle, not using.

#15Is Swift UI the problem here? Sounds like the compositor or equivalence isn't doing its job
Re: Control Center on macOS is always re-rendering its SwiftUI causing 1% CPU load
#16This is such a classic UI programming bug, and almost every UI programming framework has a way to achieve this accidentally using core components. React is notorious for this, but even in non-declarative frameworks it's very easy to get a reactivity loop on a trigger or model update and do this.
It’s way easier in declarative frameworks, though.

#17I see 0% CPU for control center here (13.6) so either fixed, or not always the case.

#18That's probably a good amount of battery life that can be claimed back once this is fixed
The fix will be ready for the next macOS Apple Event so that they can claim battery performance improvements
Meanwhile Apple is the company most actively working on better battery performance, less memory utilization (e.g. compressed memory) and other such changes...

#19What does "even though there is no UI visible" mean?
Control Center is an overlay that is only shown when the appropriate icon in the menu bar is clicked. https://support.apple.com/guide/mac-help/mchl50f94f8f/13.0/m...
Couldn't it render on demand (on click)?
Or when the mouse starts entering the target before the click at least?

The compositor doesn't render, Swift UI does.
