Cursor lag M1 MacBook Pro (2020)

I've been experiencing the same problem as described in this thread: https://www.reddit.com/r/mac/comments/oldbb9/mba_m1_cursor_glitching_andor_ghosting/


During the last few weeks, I noticed the cursor movement is lagging every now and then. I'm on M1 MacBook Pro 2020 model.


First, I noticed this while gaming when all of a sudden there was a huge delay between click and shoot and the movement was also terribly lagged. There was no such issue before.


This problem applies to the external mouse and the trackpad equally.


I use an external monitor, but the lag is there on both displays - on the external monitor and the built-in-display, also when I disconnect the external monitor.


For example, I switch the browser window and the lag appears. Then I change to another one and everything works fine, without the lag. So this problem just comes and goes.


There is no refresh rate problem for the videos even when I play UHD video on 4K monitor.


I think this is specifically a cursor problem, maybe related to GPU.


Does anyone have the same problem? What might cause this issue?




MacBook Pro 13″, macOS 11.4

Of the many things that typically slow down a Mac, you have an example of almost every single one:


Cleaners, speeder-Uppers, organizers: MacBooster is installed. These invariably end up slowing down your Mac. Get rid of it.

Finder haxies: Magnet uses a lot of system resources for things you can do manually for no overhead.

Bit torrent: Foxl -- readers forget that a bit torrent also PROVIDES their software to others subscribed to the same torrent, and uses their system resources to provide support for this at-best-dubious process. Get rid of it.

third party screen/audio recorder: mjrecorder the Mac can already capture sound at far less overhead that this third-party add-on.

VPN: may users add these thinking it improves security. They are mistaken, it does NOT improves security, it just punishes performance Orange view itopmac

File syncs ported from non-Mac environments: Microsoft OneDrive. When allowed to run at all times, this reads all your files, all the time, looking for changes. If it were a native Mac app, it would use system data strsuctures and would not need to read your files non-stop. If you MUST use this, launch only when needed, and quit when done. It is as bad as a Virus scanner.

XQuartz is really old. are you still using it for a specific purpose?

are you still using AceAgent?

are you still using Screenflowhelper? do you need it running at al times?


... and of course google Chrome, the most flagrant resource hog that is routinely run on the Mac. It would normally be classified as abandoned by its developer because its performance has not been improved in so long, but google gets a pass from most users. If you can transition to FireFox or Safari, those are much faster while maintaining a much lighter system resources impact.


Do you have a Trusted backup? your report says no time machine is set up.

Please do not tell Readers to read some other forum posts for YOUR issues.


Instead, describe them YOURSELF in your own words. That other guy did not post on the Apple forums, I can't ask them any questions, and I have to take everyones' word for it that their situation is EXACTLY the same as your situation, which my experience here tells me is almost never true.


--------

Cursor position update is done by the CPU at low priority in the background. The most common reason for seeing lag is CPU-hogging by stuff you forgot was running, but is ruining your computer's performance.


The next most common reason is that you are not actually using an Apple hardware-accelerated displays, but have accidentally used a "fake" display provided by DisplayLink, added by a third-party Dock device.

Readers can provide a personalized analysis of your situation -- provided you can provide enough information about your Mac and MacOS environment.


Use this little "Discovery" Utility, Etrecheck, to create a report of the state of your Mac. It fixes NOTHING.


Change its preferences to "allow Full disk Access; before you say "Go". Post the report back here.

Thank you for the answer.


I wrote the above text and put the link to let others know this issue is experienced by many users not just by me.


I have 16GB 8 cores version of M1 and the activity monitor doesn't show any overload.


I can't relate this problem to any activity, it looks almost random, that's not the case probably. And the restart doesn't change anything. There's a lag for some time, then it disappears and comes again later.


It is very annoying.

same it seems random... I thought that the latest update fixed it (Monterey), but it really didn't. Originally I thought it was play games that caused it. Then realized it will happen in anything (games just are just more mouse heavy than most things I currently use, ie browsing).

It seems to last shorter increments since the update, but that could just be my brain trying to cope with the fact that it still isn't fixed.
