Nvidia dedicated graphics card causes menus in the editor to duplicate

When using a laptop with an added in graphics card that's Nvidia, the menus in the editor duplicate. However, if you force the editor to use the integrated graphics card, it does not occur.

From the user:
"My laptop's OS is Windows 8.1 Pro 64-bit. I have attached the DxDiag.

In addition, I just found out that the issue doesn't occurs if I force the UE4Editor to use my laptop integrated graphics card (Intel). It only occurs if the dedicated graphics card (NVIDIA) is used rather. However, this workaround is not acceptable as a solutions since the power of the dedicated graphics card is required to run the UE4Editor satisfactorily.

Regarding this new finding, I guess this issue might be related to NVIDIA Optimus technology, which is in common use on laptops. I hope that the Epic team fixes it soon."
