upgraded my M1 2020 Macbook to Ventura 13.1 - built in display is lagging

I don't see any of the usual suspects in the report. It looks pretty clean to me. Give this a try: boot into Safe Mode according to How to use safe mode on your Mac and test to see if the screen lagging problem persists. Reboot normally and test again.

NOTE 1: Safe Mode boot can take up to 3 - 5 minutes as it's doing the following; 

• Verifies your startup disk and attempts to repair directory issues, if needed

• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)

• Prevents Startup Items and Login Items from opening automatically

• Disables user-installed fonts 

• Deletes font caches, kernel cache, and other system cache files

NOTE 2: if you have a wireless keyboard with rechargeable batteries connect it with its charging cable before booting into Safe Mode. This makes it act as a wired keyboard as will insure a successful boot into Safe Mode.

Also create and log into a new, basic, admin user account, Set up users, guests, and groups on Mac,  and see if the problem persists. This tells us if the problem is limited to your user account or is system wide.

Note:  do not launch any 3rd party apps in the account so as to not install any of the supporting files that most create.

If the problem persists then your original account has software installed that is causing the problem.

Thanks so much for the suggestion I did try turning off true tone.

Regrettably I didn't improve things at all. Also, as I posted in other responses, it still happening even in safe mode before I even select the user so it's an OS level dilemma. Not specific to my user.

This specific description bothers me.

This maybe in fact a Hardware issue.

Restart in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal.

2 - Safe Mode will also eliminate Third Party Software, extensions and drivers from loading.

It will only load the bare Minimum of core elements of the Operating System to allow the computer to function at a reduced level of performance including Visual Display

At this point and based upon the work that has been done to isolate this machines' issue >>>

Have the computer evaluated by the Professionals who have the Special Hardware Software and Expertise to diagnose the issue and offer possible solutions

As Luis suggested: download and run Etrecheck.  Copy and paste the results into your reply. Etrecheck is a diagnostic tool that was developed by one of the most respected users here in the ASC and recommended by Apple Support  to provide a snapshot of the system and help identify the more obvious culprits that can adversely affect a Mac's performance.

Then we can evaluate the report to see if we can determine the cause of the problem.

Contributor factors to the Laggy Builtin Display

1 - Running with " True Tone " enabled - image below

2 - Especially if Google Chrome is issued with several heavily javascripted Websites in each

Above is only IMHO

Thank you for posting the report. By the way you did nothing wrong, it’s just that when Old Toad his he had not yet seen that you had posted the report.

I have to teach a class in a few minutes but I will try to look at your report soon.

Is Valentine O.T. making an appearance

No. I just do Christmas and New Years. Valentine's Day is just a cheap marketing scheme to get us to buy chocolate, flowers and unmentionables for the ladies.

The only true way to know for sure if it is Hardware Issue has had a suggestion already put forth.

As for suddenly appearing upon an upGrade , Hardware can act up at any time even on an almost Brand New Machine.

Should this be a genuine Hardware issue - even downgrading to a previous version of macOS will not fix the Hardware

If the user is intent on downgrading ( which I suggest not until the machine has been evaluated )

The link below will offer possible solutions

There are two very different methods and Depends 100% on Intel or M1 /M2 Apple Silicon computer

We need more information to try and determine the cause of this issue.
