Occasional stuttering that hangs the entire UI on new 16" MBP

[embotix]

I've had the new 16" for just over a day. I've noticed about a dozen times some random UI hang-ups. They mostly last just a second or two. On one occasion, the entire UI was hung indefinitely (a few minutes). It seemed to be just the UI, since, if I hit Command-Tab, I could see it was switching between apps (the Touch Bar would show different options for whatever app I was blindly command-tabbing to).

This is a behavior I haven't observed before on a 2017 13" MacBook Pro (non-Touchbar).

I'm wondering if this is possibly related to the Touch Bar, T2, or maybe even the discrete graphics? Maybe this is normal when the OS is switching between Intel and AMD GPU?

Has anyone else observed this on their new 16" units?

Do you have kernel errors in Console.app?

Hmm I've never used the Console.app before - thanks for the tip. The next time it happens, I will check and report back.

Here's what I'm seeing in Console.app for "Errors and Faults" at the moment:

Happened again, I *think* I captured the corresponding log details in Console.app?

To get the UI to hang (it wasn't a momentary stutter, this hung the whole UI indefinitely, I had to force shutdown), I was moving the Notes app icon from one place in the dock (near the right end) to another (near the left end). The UI hung just as I was letting my finger off the trackpad to let it drop into position.

Is it possible I got unlucky with a bum unit?

You should google the IntelAccelerator prodding error you will see this has happened for years for various reasons. Hopefully one of threads will help you.

This **** happends to me as well. Im the OP on that link. Only micro stutters though, not 1-2 seconds. If you make a new admin account the Intel Error goes away, but the problem is still there. I didnt find any solution to it though by googling it. Let me know if you find a solution to the problem

If it goes away on another account it must be related to an application or setting.

Did you set up the system from scratch or did you copy over settings from another system.

Have you checked what applications you have set to automatically start when you log in?

Just the error message. The sluggish UI doesnt go away. A clean Catalina reinstall didnt help either.

1. Go to the  Apple menu and choose “System Preferences” and then go to “Energy” control panel.
2. Uncheck the box next to “Automatic graphics switching”

This slightly improved the UI sluggishness for me. The system only use the AMD GPU and shuts down the Intel 630.

Let me know if this helps you ? =)

Thanks for the tip. After noticing that these micro stutters continue to persist even after the recent 10.5.2 update, I will try this option to disable automatic graphics switching. Will report back in a day or so.

I'm throwing my lot in here. I'm experiencing this same issue for the past 3 weeks or so. I just got this computer, maxed everything. Should I return it? Is this something that will be smoothed out? It's too expensive to just hope the problem goes away.
@embotix, what the specs of your machine? I'm wondering if it has something to do with the graphics card, SSD, or RAM.

Specs
64GB RAM
2TB SSD
i9 2.4Ghz
5500 8GB

Mine was 32GB RAM, 1TB SSD, i9 and 5500 8GB. I gave up in the end and returned it.

Are you geting any GPU panics, reboots, fans at high speed right at reboot?
