Kibana Desaturates on Refresh - Not good for aggressive refresh rates

[gose]

Kibana version: 7.9

Elasticsearch version: 7.9

Server OS version: Linux

Browser version: Safari 13.1.2

Browser OS version: Mac Safari 13.1.2

Original install method (e.g. download page, yum, from source, etc.): apt

Describe the bug: Dashboard desaturates color when reloading visualizations. For dashboards that have an aggressive refresh rate (e.g., < 10 seconds), this can flicker the colors noticeably, which isn't an ideal user experience.

Steps to reproduce:

1. The attached gif is of the out-of-the-box dashboard called: [Metricbeat System] Host overview ECS

Expected behavior: I would expect colors to desaturate on a visualization (to indicate possibly stale data) only if other visualizations have been updated after a refresh and one visualization is taking longer than usual to refresh or has failed.

Apologies for the slow reply on this. I will bring this up with the team next sync. We are reviewing how to improve partial results / loading across pages and visualizations. With the addition of async UI (#81793), we may be able to remove this behavior. But we'll look into it.

We are still putting together guidelines for loading states and hope to have a starting draft this month. But in the meantime, is it possible to disable the desaturation effect when auto-refresh is on? Or if set below a certain value?

This looks very closely related to #86947

In addition to solving the problems about this issue, I would like to propose that this feature be configurable. That is, when it is enabled, it will perform the data loading feedback, but if it is disabled, do not make any changes to the visualizations on dashboard. This flickering effect can be annoying when the refresh time is short.
