Question Site loads partially until a manual refresh

[tkalfaoglu]

This is probably related to nginx, but I thought I'd ask.
Our homepage, www.kalfaoglu.net was recently updated to have several round red `highlights` icons on its homepage.
the content and location of these icons seem to change depending on if you visit the site for the first time, versus if you hit Refresh on your browser.
The first time, it does not load them correctly. But if you refresh, then they are loaded..
Nothing odd in the logs, AFAIK..
Any ideas why this is happening?
Many thanks, -t
