I just found that there are issues when trying to use Unreal Engine with the FPS overlay enabled in Nvidia’s GeForce Experience. The interface started getting a little glitchy when I tried right clicking or opening menus and it was putting the frames counter over the drop down menus. Just thought I’d let people know since it took me a bit to figure out what was going on. Turning the setting off in GeForce Experience fixed the problem.
Unsure if it’s an issue with the version of UE I’m using, but I’m on 4.13.2.
