Bug Description
This is a display bug in the Claude Code CLI, not something I can fix from within the conversation. A few things to try:

  1. Resize your terminal window - sometimes forces a
  2. Run /clear - clears the screen and may fix rende
  3. Check terminal width - narrow windows can cause

If it persists, this would be worth reporting at https://github.com/anthropics/claude-code/issues since it's a rendering bug in v2.0.73.

## Model-specific rendering issue discovered

I found that this rendering issue is model-specific in v2.0.73:

### Environment

  • Version: 2.0.73
  • Platform: Windows 11 on VMware Workstation Pro
  • Terminal: Windows Terminal

### Key Findings

  • Opus 4.5: ✅ Rendering works perfectly (no issues at all)
  • Sonnet 4.5: ❌ Display corruption occurs (same symptoms as described)

### What I Tested
Switching between models on the same v2.0.73 installation:

  1. Started with Opus 4.5 → Display was completely normal
  2. Switched to Sonnet 4.5 → Display immediately corrupted
  3. Switched back to Opus 4.5 → Display returned to normal

### Attempted Workarounds (No Effect)

  • ✅ Tested: alwaysThinkingEnabled: false → No improvement
  • ✅ Tested: VMware graphics settings → Not related
  • ✅ Tested: Windows Terminal rendering settings → No improvement

### Working Solution
Downgrading to v2.0.65 → Works perfectly with both Opus and Sonnet

This suggests the rendering bug is Sonnet-specific in v2.0.73, not a general terminal compatibility issue.

I was experiencing a similar issue. Claude Code's responses appeared blank/empty, showing only the last sentence of the output. I tried various fixes but nothing worked. Eventually, downgrading to v2.0.65 solved the problem.

Is downgrading really the only solution for now? Any ETA on a fix for the latest version?

I have a similar rendering issue too reported in https://github.com/anthropics/claude-code/issues/14613
Maybe you can also reproduce it.

Downgrading to 2.0.70 worked for me.

Worked for me too! I also had to disable the AUTOUPDATER.

djmysticist · 8 months ago

Same issue in VS Code terminal. Disabled AutoUpdater and downgraded to 2.0.72.

Maintainer Summary (Executive)

v2.0.73 introduces a Sonnet 4.5–specific rendering regression. Opus 4.5 renders correctly under identical conditions. The issue reproduces immediately when switching models on the same install and fully resolves when rolling back to v2.0.72 or v2.0.65. This isolates the defect to Sonnet’s rendering path in v2.0.73, not the terminal, OS, or VM stack.

Minimal Repro (Actionable)

  1. Install v2.0.73 on Windows 11.
  2. Open Windows Terminal.
  3. Select Opus 4.5 → rendering 정상.
  4. Switch to Sonnet 4.5 → immediate display corruption.
  5. Switch back to Opus 4.5 → rendering recovers.
  6. Roll back to v2.0.72 or v2.0.65 → Sonnet renders correctly.

Expected: Identical rendering across models
Actual: Sonnet 4.5 corrupts display in v2.0.73 only

Anthropic is doing a great job (overall)!
