After a recent update, the Claude Code desktop app transcript view has rendering issues:

  1. Text is truncated — messages are cut off mid-sentence, showing partial content
  2. Markdown not rendered — code blocks, tables, and formatting appear as raw text or are missing
  3. Content overflow — some text appears to overflow its container

Description

After a recent update, the Claude Code desktop app transcript view has rendering issues:

  1. Text is truncated — messages are cut off mid-sentence, showing partial content
  2. Markdown not rendered — code blocks, tables, and formatting appear as raw text or are missing
  3. Content overflow — some text appears to overflow its container

Screenshot

The screenshot shows a session where the assistant's response is partially rendered — text is cut off, diff markers (+109 -0) appear inline, and the overall layout is broken.

Environment

  • Platform: macOS
  • Claude Code version: Latest (updated recently, issue started after update)
  • Transcript view mode: Normal
  • Language: Mixed English/Traditional Chinese (zh-TW)

Steps to reproduce

  1. Open Claude Code desktop app
  2. Open any existing session with long conversations
  3. Scroll through the transcript — text appears truncated and markdown is not properly rendered

Expected behavior

Full message content should be displayed with proper markdown rendering (tables, code blocks, headings).

Actual behavior

Messages are truncated, markdown is rendered as plain text, and some content appears to overflow containers.

extent analysis

TL;DR

The rendering issues in the Claude Code desktop app's transcript view may be resolved by adjusting the transcript view settings or updating the markdown rendering library.

Guidance

  • Verify that the issue persists across different sessions and languages to determine if it's specific to certain conversations or a global problem.
  • Check the app's settings for any options related to text wrapping, truncation, or markdown rendering that may have been altered during the recent update.
  • Test the transcript view in a different mode (if available) to see if the issue is mode-specific.
  • Consider reporting the issue with more details about the system configuration and the exact version of the Claude Code desktop app for further assistance.

Example

No code snippet is provided as the issue seems related to the app's configuration or rendering engine rather than a specific code problem.

Notes

The issue might be related to the recent update of the Claude Code desktop app, and it's unclear if this is a widespread problem or specific to certain environments. The mixed language setting (English and Traditional Chinese) could also be a factor.

Recommendation

Apply workaround: Given the information, it's safer to first try adjusting settings or reporting the issue for a potential fix in a future update rather than attempting any unsupported modifications.
