[Bug] Chat output rendering corrupted with missing text lines

This happens for me in PowerShell 7.5.4 in Windows Terminal on Windows 11 Pro, also.

Happening for me in Windows 11 Terminal. Completely unusable.

The output is crash also.

Same thing happening

I downgraded to 2.0.72 and it works again. Disabled automatic updates first.

Same for me since version 2.0.73. The output is completely unreadable and missing major parts of the content. It looks unstructured and leaves a lot of huge gaps between the output text.

same issue in Win 11 running version 2.0.73

same thing happening

Also getting this on PowerShell with native installation on v2.0.73

Can confirm happening with Positron IDE and Rstudio IDE.

Same on Windows 11 26200.7462

# uninstall problemmatic verion
npm uninstall @anthropic-ai/claude-code -g

# install older version
npm install @anthropic-ai/claude-code@2.0.72 -g

# Check version 
@ Should output: 2.0.72 (Claude Code)
claude --version

$ Disable automatic updates
set DISABLE_AUTOUPDATER=1

work around for Windows:

npm install -g @anthropic-ai/claude-code@2.0.72

in a bat/cmd:

set DISABLE_AUTOUPDATER=1 && claude

how is Windows support not being tested before any public release?

Does anyone know if there is any statement by Anthropic on this? From the issue it seems nobody's even looking at it. However, I find it to be a fairly critical mishap.

Same issue here, looks like this a new bug since today?
Text is being aligned center terminal and some text is being cut off.

Would like a patch as soon as possible...
I can't work with Claude like this

Decided to install to WSL instead, maybe that's the best approach anyway rather than use the powershell terminal.

Same issue using powershell.. PSVersion 5.1.26100.7462

Same issue, just started with latest update.

Very interesting @rubrical-studios and @shailensukul I have tried versions 2.0.74, 2.0.73, 2.0.72, and 2.0.70 and i still get the same whitespaces and etc.

After some playing around: I was using Claude Code Extension and set it to those specific versions and same error. Installing version 2.0.72 globally works in terminal.

for me 2.0.72 fixes the bug. 2.0.73 is unusable.

Same on Windows 11 26200.7462 `` # uninstall problemmatic verion npm uninstall @anthropic-ai/claude-code -g # install older version npm install @anthropic-ai/claude-code@2.0.72 -g # Check version @ Should output: 2.0.72 (Claude Code) claude --version ``

It will auto-update unless you block it. Turns out there may be other bugs for "settings" that should but do not block the auto-update feature. This approach works:

in a bat/cmd:

set DISABLE_AUTOUPDATER=1 && claude

Guys I didn't sign up for dev/nightly releases.

For Powershell reverting the native install temporarily with this command works (until autoupdate happens again if not disabled):

curl -fsSL https://claude.ai/install.sh | bash -s 2.0.72

I downgraded to 2.0.72 and it works again. Disabled automatic updates first.

Confirmed working. Use npm install -g @anthropic-ai/claude-code@2.0.72 in powershell to downgrade.
setx CLAUDE_CODE_DISABLE_AUTO_UPDATE 1 in powershell to disable autoupdate.

Same issue - hope this gets resolved soon.

Experiencing the same issue. In my case, I see excessive blank lines/gaps between output sections rather than completely missing text.

• Platform: win32
• Terminal: PowerShell 5.1, PowerShell 7.5.4
• Version: 2.0.73
• Node.js: v25.2.1

A different workaround for those too lazy to downgrade the version is to ask it to write the final summary to a file or to post into the PR or Issue it is about (if any).
