I recently started learning Wordpress, and i noticed something quite disturbing: Under most circumstances, every page load would cause parts of it to "flicker".
For instance, if i use the generic "twentyseventeen" theme, The famous header banner would flicker, each time i click a different link from the menu.
It feels as if "something is wrong" with the caching. I tried it both on my remote server and localhost- same result.
It seems that the problem is more severe on Chrome than on Firefox, but it's quite evident on both.
Here is a link to my example site: https://wp.ibrod83.com/. If you play with the top menu links, you should notice it.
I'll mention that i didn't make any special configuration, neither on the remote nor the local one.
Is this "normal" for WP? Can it somehow be fixed?
