openclaw - 💡(How to fix) Fix Control UI webchat: duplicate assistant messages after update to 2026.4.24 [1 comments, 2 participants]

TL;DR

The most likely fix for the duplicate assistant messages in the webchat Control UI is to revert to a previous version of OpenClaw or wait for a patch for version 2026.4.24.

Guidance

• Review the changes made in version 2026.4.24 to identify potential causes of the regression, focusing on UI rendering and message handling.
• Compare the current behavior with the similar issue #5964, which was closed in February 2026, to see if any of the previously suggested fixes could apply.
• Test the webchat Control UI with different types of messages and scenarios to ensure the duplication issue is consistent across all cases.
• Consider reaching out to the OpenClaw team for further assistance, given that they verified the issue during a troubleshooting session.

Example

No specific code snippet can be provided without more details on the OpenClaw API or the webchat Control UI implementation.

Notes

The issue seems to be specific to version 2026.4.24 of OpenClaw and does not affect the backend transcript, indicating a UI rendering problem. The fact that page reload does not fix the issue and it's a regression from a previously closed issue suggests a code change in the new version might be the cause.

Recommendation

Apply a workaround by reverting to a previous version of OpenClaw until a fixed version is released, as the current version introduces a regression that affects the user experience.
