Browser console elements are blinking like they are rendered although they are not, from unknow reason

Question

I have some pages which use a common module on application. From unknow reason I keep seeing the tr's elements on the browser console blinking in a purple like they are rendered again.

I don't see reason for that behavior and it's unwanted.

How can I debug or check in another way what's causing it

See the attached image please

EDIT: I've tried to add onChange life cycle to my component to see if there are changes that I'm not aware of. But it doesn't triggered at all (when this scenario happens)

Answer 1

The reason is that something in your code is constantly triggering the angular change detector. An example of such action can be wrong usage of some component lifecycle hook like ngAfterViewChecked or ngDoCheck .
