This mouse lag has been bothering me for over a month, driving me crazy, and I couldn’t figure out the cause until now. It turns out the issue was with Karabiner-Elements. When the “Modify events” option is enabled for the mouse under “Devices,” any CPU spike—such as opening a new Chrome tab, loading a website, or accessing settings—causes the mouse to lag.
here's a video demo

When I untick it, the mouse behaves normally again. In the video, it might appear a bit laggy sometimes, but that’s because I’m moving the cursor very quickly, and the video is likely recorded at 30 FPS.

Can you reproduce this issue with a clean profile?
I'd like to determine whether the problem is caused by Complex Modifications.

You can add a profile by following these steps.

I'm not sure what mouse you're using, but mice with extremely high DPI might experience this issue.
That said, I don't experience any problems with my mouse, which has a DPI of 8200.
If your mouse has an even higher DPI, reducing the DPI might mitigate the issue.

It still occurs even on a clean profile without any complex modifications. This is definitely a new issue. I’ve been using the same mouse (Razer Naga Trinity) for several years and haven’t reprogrammed it since I first got it.

I’m not sure about the DPI settings, but when I access my Windows machine, I’ll double-check the DPI and lower them to see if it makes a difference.
