Often Slowdowns, Lags, Freezes on all Mac Devices

[archerypigmuffin]

Hello.

I'm using macOS Version 14.6 (Build 23G80) and I need assistance.

I'm experiencing following issues with DisplayLink software and/or hardware: We have noticed intermittent mouse lag, glitches and latency issues, on all of our Mac machines running Display Link Manager. We have also seen it on machines running macOS 15.1. This issue has been hard to track down and intermittent, fixing itself for some time and then happening again later. Moving the mouse between displays seems to sometimes trigger it, also seems to happen when moving or closing windows. But also the issue happens sometimes for seemingly no reason.

All of these machines have been on Display Link 1.11.0, one of the users has a personal machine on 1.9.0 doesn't think they have had any of the issues, also running macOS 15.1. This leads us to believe it could be an issue on display link 1.10+

I'm also facing similar issues. The slowdown is most noticeable when using terminal based software.
iTerm macOS 15.1
DisplayLink version 1.11.0

Can totally confirm that, that this issue is gone with DisplayLink V10.9. Downgraded from the latest release available and the described problems are gone.

Hi archerypigmuffin,
Thanks for getting in touch, Unfortunately you didn't put the logs here as an attachment just the tool to collect them. Nevertheless, I would very much like to understand the problem and reproduce it on my setup. Can you elaborate a bit on when it occurs and confirm on which macOS the problem occurs? Is it only on macOS 15, or have you also noticed it on macOS 14?

After the OS upgrade to Sequoia, the mouse is now erratic on the second screen. It is erratic and jumpy almost to the point of being unusable - but it was fine before the OS upgrade.

Obviously, I will not retrograde my computer, so please make a fix to your software. Judging from the many other complaints of the same or similar problems, this is widespread, well-known, and common.

And since joining the forum to research this matter, I have not seen any solutions posted - I've only seen the company post replies telling the poster to send them the logs... If you want me to do that, you'll have to explain how.

Looking forward to your response.

thanks dbienkowski,

That's embarassing regarding the upload, here's the right file. Yeah we have had this on devices from MacOS 14.6 to 15.1.

The first user who reported it was on 15.1, she complained of mouse jitters as well (similar to the user above) so we stopped updating the machines but still get the lag/freezing described on MacOs 14.6. I'm not sure if 15.1 is truly worse as we stopped updating and rolled back our users but obviously, we'd to be on the newest version if fully supported by you.

I've personally downgraded all the way to display link 1.9.0 and I still have the issue sometimes, I feels like it's less often but I still get it. Tracking on Activity monitor there doesn't seem to be any spike in resources used at the time of the issues, sometimes 'WindowServer' seems to spike but it only ever spike to ~50% of a very low CPU load anyway (>80% CPU idle) (Apple M2).

We've been running a maximum of 2 connected displays, with the laptop screen being the 3rd, all users are really just running Google Chrome and Cisco Webex, well they should be at least with other management tools running in the background of course as well, crowdstrike, etc.

The machines are very powerful for what they are doing and can't be the source of the problem, they are not overheating or throttling in any way, it's something else related to your drivers/software.

I'm sorry we can't give you any further tips for investigation, the issue feels pretty random, it does seem increase in frequency the more windows, (not tabs) the users have open, I can pretty successfully 'encourage' it by opening all kinds of windows and having them in view on my screens, but even then it still only pops up anywhere between every 5 mins and every hour.

We have a couple of Mac Mini's out there, I can check with those users if they've had the issue, but they haven't reported anything, that could be a hint that it's only related to laptops but that's just a hunch.

In the meantime I'll keep working my way down your legacy releases and see if there's a magic bullet there.

Cheers,
