Messages duplicated in Web UI (v2026.4.14)

[mental crescent]

Hi, I'm experiencing a bug where my sent messages appear twice in the OpenClaw Web UI, even though I send them only once (confirmed via DevTools console - no duplicate requests). This happens across multiple browsers (Opera, Chrome) and devices (desktop, phone). Each connection to webchat seems to trigger a duplicate render. The issue persists after gateway restart.

Steps:

1. Open OpenClaw Web UI
2. Send a single message
3. Message appears twice in chat

Expected: message shows once
Actual: message shows twice

Can reproduce on demand. Anyone else seeing this?

Let me check the docs and repo before I guess.

Yeah, that sounds like a real WebChat/Control UI bug, not just you.

There are a few pretty similar reports already:

• https://github.com/openclaw/openclaw/issues/5964
• https://github.com/openclaw/openclaw/issues/35860
• https://github.com/openclaw/openclaw/issues/2959

Your “single request, duplicate render, cross-browser/device” detail makes me think client-side WebChat state/WebSocket/history reload, not duplicate sends.

Can you paste these first:

openclaw --version
openclaw status --all

And 2 quick checks:

1. Does a hard refresh make the duplicate disappear?
