I’m still not seeing the hanging of the first slide on both of my computers…. but I also noticed that the captions are different if you are using my circumference custom style for it. The hanging of your first slide though won’t be the theme, more likely there is a delay relating to the plugin’s script on your computer(s). The KenBurns effect is very resource heavy, so this could be causing the issue for you. What happens if you change the effect to fade or something else, then see what happens?
