claude-code - 💡(How to fix) Fix [Bug] UI layout breaks on terminal resize with corrupted table and code display [1 comments, 2 participants]

[{"error":"Error: NON-FATAL: Lock acquisition failed for /Users/morris/.local/share/claude/versions/2.1.126 (expected in multi-process scenarios)\n at r86 (/$bunfs/root/src/entrypoints/cli.js:2768:2177)\n at HD8 (/$bunfs/root/src/entrypoints/cli.js:2768:1257)\n at processTicksAndRejections (native:7:39)","timestamp":"2026-05-02T12:29:01.302Z"}]

TL;DR

The issue may be related to the Ghostty editor's handling of window resizes, causing the Claude code chat UI to break, and a potential workaround is to avoid resizing the window or use a different terminal.

Guidance

• The error message suggests a potential issue with lock acquisition, which might be related to the multi-process scenario, but it's unclear how this directly affects the UI distortion.
• To mitigate the issue, try avoiding window resizes or use a different terminal to see if the problem persists.
• The fact that stopping the session and clearing the chat fixes the issue temporarily suggests that it might be related to the rendering or state management of the Claude code chat.
• Consider reporting this issue to the Ghostty editor or Claude developers, as it might be a compatibility problem between the two.

Notes

The provided error message does not directly point to the cause of the UI distortion, and without more information about the Ghostty editor's rendering mechanism or the Claude code chat's implementation, it's challenging to provide a definitive fix.

Recommendation

Apply workaround: Avoid resizing the window or use a different terminal, as this seems to temporarily resolve the issue, although it's not a permanent solution.
