What's Wrong?
Typing on the Windows system has very high latency.
I've noticed that Claude Code has always been quite sluggish in the Windows environment—I've tried it in both the VSCode terminal and the Android Studio terminal, and both were extremely slow. The Windows Terminal combined with Git Bash wasn't exactly smooth either, but it was still usable. Today, however, I found that Claude Code has become so laggy it's practically unusable;
What Should Happen?

also facing this as well
Crazy annoying isnt it. +1 suffering
If you guys find a fix pls let me know
I'm experiencing the same issue..
Same here!
Same
I have the same problem. It was normal before, but it suddenly started to happen today.
You just need to roll back the version to npm install -g @anthropic-ai/claude-code@1.0.113 to make it work normally.
Just to confirm, everyone facing this is on Windows?
+1, native windows, yes
yesterday it was heavy input lag, today it's impossible to type a single character
+1 yes windows
this also happens in macOS
vscode, cursor, terminal, all with input lag...
Claude Code v1.0.115sAME hERE
Been bad all day; definitely the powershell version as I’ve got WSL also installed and no issues with Linux environment.
+1 windows
Can't backspace characters properly either possibly related to #1853 (which as a workaround btw you can use ctrl-backspace to delete word by word and that'll work)
workaround:
1) npm uninstall -g @anthropic-ai/claude-code
2) npm install -g @anthropic-ai/claude-code@1.0.110
or 1.0.114 , for me 1.0.110 , works really well.
3) {
"env": {
"DISABLE_AUTOUPDATER": "1"
}
}
put this into the settings.json file from under your user - dir : .claude
enjoy... no lag.
+1 on windows
@n3tw4rl0k This workaround really works — thanks a lot!
This input box latency should be addressed with the 1.0.117 update.
there is no change for me. still experiencing the issue
1.0.117seems to have resolved the issue for methat fixed it!
1.0.117 still experiencing the issue in native Windows, had to roll back to 1.0.113 again.
Agree with comments above; performance is better in that it can be used but still bad with periods of unresponsiveness especially whilst models are working. Worse if sub agents running, unable to type at all.
This bug should be reopened. Even though the behavior has improved with 1.0.117, as explained by previous comments, while claude code is thinking or interacting with the model in any way, the input is completely blocked. The useful function of typing something to be processed later, even being editable in the meantime, makes no sense in the current status because it is impossible to input anything.
Same here, still facing the issue. When opening claude code, unable to type anything sometimes.
