Issue

After an update to Qt WebEngine 5.15.0, web extension zones freeze after a dashboard has been duplicated.

For extensions, they also freeze if something was running within the extension and you click away from the dashboard during an action. This also happens without duplication.

Once the zone freezes you are unable to reload the web and extension zones from the context menu and only resizing the extension seems to bring it back and make it responsive again.

Environment

Tableau 2020.1.3, 2020.4.1, and 2021.1

Resolution

Updating the Qt library to the latest version should fix the issue.

Cause

This behavior is caused by a defect, ID 1251641, that is currently under investigation.

Additional Information
