scrolling delays in osx Ventura

[ctrlok]

Hello.

I'm experiencing a problem with scrolling time-to-time after a MacBook sleeps. I don't know how to reproduce, but still, it happens every 2-3 days.

How it looks

When I'm scrolling via the touchpad — it doesn't scroll smoothly, but with delay and like sending different commands simultaneously.

How can it be fixed

It can be fixed by killing the karabiner_grabber process (kill -9)

After the process was killed (and restarted), everything smooth again

What version I'm using

OS X Ventura 22A5365d (latest beta, but it happens on previous betas as well) Karabiner: 14.10.0

logs

There are not many details in the logs. Log was copied after glitch started to happen and before I killed karabiner_grabber
