Reflection UI menu blincking and missing info on v22


we upgraded Dremio to v22.1.1 community Edition and observed that the UI is blinking really fast and in a “random” manner on the Reflection information of Datasets.

Some information disapears despite the reflections still being OK. Eg. :

Could you tell if it is a known issue and available solutions ?

This is not a known issue. That location you highlighted is where the real time reflection availability and refresh status is shown. You could open the Chrome browser dev tools and look at the REST API calls to see if there is anything helpful there.
