We noticed on a recent project that there is some kind of delay in loading the page. You see it when you almost immediately move the mouse over the menu. The mega menu is then only partially loaded. If you wait a few seconds, the menu will be displayed properly. Do you know what is being loaded extra at that time? We have enabled Enfold caching.
I am curious if anyone has experience with this.
Have you tried disabling all active plugins to see if the issue persists?
