Background image does not load on Petition Wechange theme

Hello - I’m using the Petition Wechange theme. It has always worked fine, but now for some reason, the background image does not load when a user first visits the site. Upon visiting the site, the background image is blank…but if one refreshes the page - it then appears.

Any advise on how I may fix this issue? Thank you! Here’s the site: http://justiceforstanrothenberg.com/
