I have a weird issue going on. I have released a new web app for my users. In this app, I load a document from LF with this syntax.

For the most part, it works. On my computer, it's almost 100 percent. 
My new users for some reason are having this issue where it looks like everything loads, the document is just not there. However, if they click the "DETAIL" tab that is vertical on the right side of the iFrame, when the details tab is expanded, the document shows up. They close the detail tab and the document is still there. 
It's a weird glitch that doesn't always happen. 
The questions I have are, has anyone ever dealt with this? What could I look for to try and troubleshoot the issue? The documents are always PDFs and I'm not sure if that is part of the issue, too. It's hard to troubleshoot since it seems to work on my computer. 
Thank you in advance.
