Running Weblink 11.0.2411.10 and a few users have reported issues with documents displaying strangely. See attached image for an example.

In this instance, I'm able to view the document just fine, but it displays broken into pieces on the user's screen. It's almost as if the document viewer is trying to display it as thumbnails. 

I had the user clear her browser cache and try reloading but that didn't fix the issue. 

Any thoughts on what's causing this and how to fix it?
