Terminal output hangs every few seconds

[LucasIME]

Hey! I've just got a new M1 Mac and was reinstalling my terminal setup and noticed something weird. My terminal output seems to hang in somewhat constant intervals. I managed to pin it down to this plugin. If I disable zsh-syntax-highlighting, everything works fine. But if it's enabled, the typing experience becomes extremely unpleasant, as it basically hangs every 1 second. It happens regardless of the terminal client I use (Terminal App or Alacritty) or if I'm inside a tmux session or not.

Here is a video of what it looks like if I just hold a key down:

Not sure if this is a known issue? My previous setup on my old laptop seemed to work just fine.

Zsh version: 5.8.1 Oh my zsh version: commit b9be3a43b4da579299b4426b1ba9121f746e2555 from master zsh-syntax-highlighting version: commit 122dc464392302114556b53ec01a1390c54f739f from master

Let me know if you need any other info to track this down. Happy to help with the investigation and possible fix

@LucasIME I'm seeing exactly the same issue here with a similar setup as yours. I'm curious if you installed zsh-syntax-highlighting using brew or from source?

[CVirus]

Here is an interesting find: I noticed that I have multiple tmux sessions (tmux ls) spawning even if I'm not starting them. So I suspected something might be off with tmux-continuum or tmux-resurrect and disabled them.

Now, the issue is no longer reproducible for me.

@CVirus I installed from source.

I noticed the issue disappear after a while. I noticed that SentinelOne scanner running on my work laptop was interfering with it somehow? I don't know if intercepting some system call or just the high cpu usage from SentinelOne. But upgrading SentinelOne made my issue with zsh-syntax-highlighting disappear.

@LucasIME Interesting, I also have SentinelOne running on my work laptop. Do we happen to be working at the same place or is SentinelOne very common on work laptops?

[LucasIME]

Judging from the companies listed in our profiles, I don't think so, haha. But yeah, think SentinelOne is quite common.

For reference, upgrading it to version 22.3.2.6355 was what fixed my issue.

Thanks for the reminder to update my company in my profile 😄

Closing as no longer reproducible for either of you. Easiest issue I've ever dealt with :-)

I have the same issue on my M1. I don't think I have the SentinelOne installed, at least it doesn't show up in Launchpad. Also, sometimes (but not systematically), I start typing a command like vim and just the 1st letter shows up. After about 5-10s the rest.

I'm using:

• zsh 5.8.1 (x86_64-apple-darwin22.0)
• tmux 3.3a
• z-sy-h from master commit 754cefe0181a7acd42fdcb357a67d0217291ac47

I'm actually still seeing the same issue, unfortunately.
