What's Wrong?

Note to maintainers: This bug is about the consumer Claude desktop app (the macOS/Windows app for chatting with Claude on the Pro/Max plan), not the Claude Code developer CLI. I'm filing it here because support directed me to this repo and no public bug tracker exists for the consumer desktop app. Please route or relabel rather than closing as "invalid" — affected users have no other public escalation channel.

What's Wrong?

When opening a chat in the Claude desktop app on macOS, the chat title bar, model selector, and input box all render correctly, but the entire conversation message area renders as blank white space. The chat content is not visible until I press Cmd+R to force a page reload, after which the content paints normally.

This affects nearly every chat I open. The Cmd+R workaround works but must be applied repeatedly throughout a session. The bug started May 15, 2026 and has persisted across multiple troubleshooting attempts.

Environment

• OS: macOS 15.7.4
• App: Claude desktop app v1.7196.1 (consumer app, not Claude Code)
• Plan: Max
• Memory: Activity Monitor shows ~178 MB at idle (no resource issue)

Troubleshooting Already Completed

• Quit and relaunch — no effect
• Full app reinstall — no effect
• Full macOS reboot — no effect
• Help → Troubleshooting → Clear Cache and Restart — no effect
• Help → Troubleshooting → Reset App Data — no effect
• Deleted a chat suspected of corruption — no effect

Diagnostic Note

The Cmd+R workaround consistently fixes the render confirms this is a UI rendering/state bug rather than a backend, data, or resource issue. The chat content is present in memory; the view layer just fails to paint until forced.

Cross-Reference

Support ticket conversation ID: 215474327248202. Support directed me here after initial troubleshooting steps did not resolve the issue.

What Should Happen?

Expected Behavior

Chat content should render automatically when a chat is opened, without requiring a manual page reload.

Actual Behavior

Conversation area renders as blank white space. Cmd+R forces a re-render and the content appears correctly.
