Converted Dashboard to new UI CPU now 40%

Folks is there any way to diagnose a race condition in my Lovelace dashboard. Converted it using the new UI convert. Now my CPU is pegging 40% only on the Dashbaord page.
HASOS is doing nothing crazy. this is all local browser running hard. Click off the dashboard and it drops back to 5%. Poor old laptop fans is screaming.

Any guidance appreciated.
