I'm not using nUI, but I use SunnArt Viewport which I'm assuming is the same sort of code you use in nUI's viewport. So I've posted up some screenshots. My dual-screen layout illustrates the bug in a much more obvious fashion so hopefully this will help the devs out in fixing this issue. I can honestly say that since I hop two monitors, this bug literally makes Throne of Tides unplayable, as my "focal point" (center of the screen) is smack dab in the middle of the two monitors - making the monitor bevels split the screen so unnaturally that I can't make head from tails where I'm standing or going.
I've uploaded full resolution versions of all these images and a few more to my website:
