21:9 and 5:4 screen interfering/ splitting between screens

Hi!

I encountered the following bug, when I want to play on my 21:9 2560x1080 monitor, the game opens on the 21:9 one and then shift between the lower 1280x1024 and the 21:9 screens.

I'm using a GTX 1070 and a i7 7700k, with nVidia 417.35 driver.
The menu and ingame resolution looks like 1280x1024.
How can I force the game to only launch on the 2560x1080 screen, with the native resolution?

Are you saying the game transitions between 2 monitors or ?

Ensure that you do not have Nvidia Surround configuration of your monitors.
