Menu and UI disappeared in fullscreen mode

[AgeOfLori]

It works very fine in windowed/borderless mode. However, if I change into fullscreen mode, all the menu and UI are missing. 

Weird thing is, I can see the main menu, but not the UI or menu that seems to be 'overlay' 

Although I can't see the options menu, I can still control it with my keyboard.

I'm using 6 monitors eyefinity (5760*2160), and 2 290s crossfired. This error does not happen when using only one monitor (1920 * 1080) but anything above that, the problem happens.

I tried both DX 11 and DX 12, but same.

Sounds like a driver issue - you can report those here:
