Webchat control UI (openclaw-control-ui): sent messages don't appear immediately after hitting send.

Webchat control UI (openclaw-control-ui): sent messages don't appear immediately after hitting send. They only render once the agent starts responding, causing a 1-3 second disappearance. Looks like missing optimistic message rendering on the client side. Running OpenClaw 2026.4.15 on macOS."

I’m checking the docs and source to see if this is already understood on current main, then I’ll give you the cleanest next step.

I found what looks like the exact race in current source, and there’s already a guard for it on main. I’m checking whether that likely landed after 2026.4.15 so I don’t send you in circles.

Can you paste openclaw --version?

I dug through current source, and this looks like a real UI race, not just “missing optimistic rendering”. There’s already a fix on main for:

“skip chat history reload during active sends… delays the user message card from appearing until the first LLM delta arrives”

That matches your symptom almost exactly.

I’d try this first:

openclaw update
openclaw doctor
openclaw gateway restart

Then hard refresh the Control UI tab.

If it still happens after that, please file a GitHub issue with the exact openclaw --version output and a short screen recording: https://github.com/openclaw/openclaw/issues
