[{"error":"Error: NON-FATAL: Lock acquisition failed for /Users/manikantagonugondla/.local/share/claude/versions/2.1.118 (expected in multi-process scenarios)\n at ai_ (/$bunfs/root/src/entrypoints/cli.js:2756:2177)\n at IK8 (/$bunfs/root/src/entrypoints/cli.js:2756:1257)\n at processTicksAndRejections (native:7:39)","timestamp":"2026-04-23T21:06:04.795Z"}]

TL;DR

The issue might be related to the terminal or TUI rendering, and checking the terminal settings or updating the version could potentially resolve the issue.

Guidance

• Verify if the issue persists in a different terminal or environment to isolate the problem.
• Check the terminal settings in Ghostty to see if there are any options related to scrolling or rendering that could be adjusted.
• Investigate if the error message "Lock acquisition failed" is related to the issue, potentially indicating a problem with file access or concurrency.
• Consider reporting the issue with more details about the TUI and Claude code setup for further assistance.

Notes

The provided error message seems unrelated to the described issue, but it might indicate a broader problem with the application. Without more information about the TUI and Claude code, it's challenging to provide a more specific solution.

Recommendation

Apply workaround: Given the lack of clear information about the cause, trying a different terminal or adjusting terminal settings might provide a temporary workaround until a more definitive solution can be found.
