I acknowledge that:

• I have reviewed the FAQ and confirm that my issue is NOT among them.
• I have searched the Ghostty repository (both open and closed Discussions and Issues) and confirm this is not a duplicate of an existing issue or discussion.
• I have checked the "Preview" tab on all text fields to ensure that everything looks right, and have wrapped all configuration and code in code blocks with a group of three backticks (```) on separate lines.

Long shot since it looks like you can reproduce this with a blank config, i.e., no global keybinds, but I'd recommend trying to reset accessibility permissions following the steps here: #9047 (comment). There have been some issues with these not getting properly carried over when upgrading macOS version.

still freeze after resize

[danielwe]

Hm, this has never been a problem for me. It's gonna be hard to debug until someone's able to reproduce. As a first step, I recomment completing the initial post with the output of ghostty --version (it contains more than just the version number) and the logs that appear while resizing.

To get the logs, open a separate, non-ghostty terminal, and run sudo log stream --level debug --predicate 'subsystem=="com.mitchellh.ghostty"'. While this is running, open a Ghostty terminal and do whatever it takes to trigger the problem. Then go back to the other terminal, stop the log stream (Ctrl+C) and copy the output here.

I've updated the version in the initial post. I’ve been using Ghostty for months and never had any issues. I started experiencing this problem today after a macOS update.

[danielwe]

Thanks! Does the problem persist if you use a different shell than fish?

[TiboCiteo]

Ur welcome. I Tried with a different shell and it still freeze.

[ruedigerha]

Hi, just wanted to add that I experienced similar freezes after updating to Tahoe 26.1. I was already wondering why I couldn't find any reports about it. I am using fish as well, and a 100% reproducible freeze on my system is that right after starting Ghostty, I type a char and then try to complete the fish suggestion with "cursor right" key (it's working fine in other terminal apps).

I found out that at least on my system, this is linked to the "Secure Keyboard Input" setting. If I disable it, I don't get any freezes.

(I just checked with resizing the window and I get freezes, too, with "Secure Keyboard Input" on, but none when I turn it off)

[danielwe]

To be clear, the default is for the menu item to not be enabled. Does that setting fix the problem for everyone here? I suppose we may still want to consider this a bug, I'm just asking for diagnostic purposes.

[TiboCiteo]

That settings fix the problem for me

[nickytonline]

I found out that at least on my system, this is linked to the "Secure Keyboard Input" setting. If I disable it, I don't get any freezes.

Same for me on my MacBook Pro M2. On my work laptop, MBP M4 Pro, no issues though. 🤔

[oleksiimikhno]

Oh, my god. It helps me too (I was getting freezing time to time, but when using the same terminal with an SSH connection, everything was fine), only switching windows helped me. MacOS 26.1 M1 Air and M4 Air

[AuthorProxy]

Did you also try #9047 (comment)? Just to double check that it doesn't address the problem

this is not working!
