Page loading issues in Upfront

Greetings!

I'm having this issue where pages won't load all the way, or will load wrong if the screen/window isn't open and visible. For example, if I click a link to a different page and switch tabs, then go back to the opened link, the page didn't load properly. Shortcode/plugins and images won't be loaded and/or displayed properly etc.

Here is a screenshot to show an example:

Not sure what's happening here. Whether it's a plugin conflict etc.

Hope ya'll can help!
Much Love,
