Icon Glitch on Refresh FeatureLayer

[fb1]

Hi,
out of necessity I had to load the arcgis js sdk locally,
and I noticed a problem that I didn't have before and that I couldn't solve,
in a nutshell I have 3 featurelayers on the same zoom level,
one is a shapefile so let us not consider it, and the other two are derived from a geojson with points .
Both featurelayers have a refresh rate of about 10 seconds,
depending on how these two are loaded the last one has a strange glitch at refresh which the other one does not.
A black rectangle appears on the icon for a fraction of a second, which is very annoying.

without taking into account the third layer of the shapefile i noticed that leaving only one of the two layers active with the icons does not cause this problem, so when I go to put the second layer back on, it starts glitching again

The problem was the version of angular and related libraries (angular 15, zone.js 0.13.0 etc.).

after updating angular to version 17 I no longer had any problems
