Hi Travis,
This sounds more like a Graphic Driver or Graphics Card problem. You might try switching out the Graphic Card if that is possible on the system.
Another outside possibility might be a corrupt user profile, so you could create a different profile on the machine and try it. However, my guess would be the Graphics Card is failing.
Are you also certain there are no other Office add-ins loaded that might be causing this. Start Word in Safe Mode and see if this clears the problem. If it does, then systematically disable add-ins one at a time until the culprit is found.
Hope this helps
