Thanks for the bug report. Do you suspect this might be a regression? If so, could you confirm that downgrading to 0.100.0 fixes the problem?
Works in 0.99, but not in 0.100.
So it's something in 0.100 not 0.101
Still happening in v0.104.0
I experience the exact same thing starting 0.101, was hoping 0.104 would fix it but it's still present.
Day #13 of using a CLI where typing is slower than Windows 95.
@Cleroth, we don't have a repro for this. Without a repro, there's not much we can do.
You may need to do some investigation or diagnosis on your own to identify clear repro steps and/or find a root cause. One option is to clone the codex repo, build from source, and ask codex to help you diagnose the problem.
Did you actually try in Windows Terminal?
You could've said earlier if you couldn't reproduce.
I think a git bisect would be easier than trying to get codex to guess the problem blindly.
I've never built something with rust but I guess I'll give it a go.
This is the commit that causes the problem b4ffb2eb5852d451388f8d4d928e4fec762e1b78
For what it's worth, I set it to 1ms and the typing improved quite a bit while the pastes are still working correctly. Haven't tried with VS Code though.
Thanks for investigating. Yeah, it has been really tough to find a solution to the paste issue on Windows that works across different terminal emulators and doesn't have bad side effects like noticeable lag.
Having this same issue on windows 11 when typing feels laggy and unresponsive. It was previously not this way.

@etraut-openai any hints on doing something about this? While it's an easy fix on my end I have to manually update and build codex every time, which is less than ideal.
Having same issue on windows 11. I'm using vscode terminal that is ssh'd into a linux box
FYI, setting
disable_paste_burst = truein ~/.codex/config.toml solves this problemTo be honest I just bit the bullet and started using Codex on WSL. Just a bit of setup but the experience is superior. No lag, less sandbox issues, ...
Environment:
Confirming this issue is still reproducible on the latest Windows desktop app version (2.1.89). Adding this report for tracking purposes.
Same problem with the latest OpenAI Codex CLI 0.121.0 on Windows 11 2025H2 for me. It is really annoying. I'm running on a pretty high-end development and gaming workstation.
I'm doing heavy video processing work, software development, and gaming, on this system. Everything else is working flawlessly except that Codex CLI has the slow typing issue.
Same issue here. Windows 11 + Windows Terminal. Don't have any issues with Claude Code.
This issue should be fixed by this PR in the next release.
No, no it did not fix it.
works for me
@plasticalligator, this issue was fixed. If you're seeing similar symptoms with a recent version of the TUI, then it's a different issue. In that case, please open a new bug report and provide all of the information requested in the bug report template.
