if the hud-service is consuming 100% of one of your CPUs in a poll
loop, it could indicate an issue with the service or its configuration.
Here are a few steps you can try to address the problem:

Restart the hud-service: Restarting the hud-service can help resolve
temporary issues. You can do this by finding the appropriate command for
your operating system and executing it. For example, on Linux, you can
try "sudo systemctl restart hud-service".

Check for updates: Ensure that your system is running the latest version
of the hud-service. Updates often include bug fixes and performance
improvements. Update the service if a newer version is available.

Investigate system logs: Check the system logs for any error messages or warnings related to the hud-service. Logs can provide insights into the underlying cause of the high CPU usage. Review the logs to identify any specific errors or issues and take appropriate actions.

Disable or reconfigure hud-service: If the high CPU usage persists, you can try disabling or reconfiguring the hud-service. Refer to the documentation or community resources for your specific operating system to learn how to disable or adjust the service's settings.
