Widget details flapping

Hi all, just a minor gripe but I noticed that when I turn on the deails display under the dashboard widgets, all details stay there permanently, except the grid meter widget details. The detail display keeps flapping in irregular intervals (closes and opens gain after 1-2 seconds). I am accessing VRM with a desktop browser.

I have checked the local console logs but I cannot relate this to a loss of connection and all other widget values are updated during the flapping so it does not seem to be a network issue.

What does this flapping mean or indicate?

Thanks!
