Quadruple image instead of clean stereo image

This is an issue I currently get in the Unreal Engine 4 Arcade-Brawler WWE Battlegrounds. The game has no proper true fullscreen option (it's Borderless Window), so it even doesn't render in 3D. Thanks to the suggestion of Skyrimer though, you are able to force 3D Vision by adding "-window-mode exclusive" to the Steam launch-options. Now the game renders in 3D but it has one weird issue: You don't get the usual stereo image but a quadrupled image instead. So with 3D-glasses on, you get a stereorized 3D image but you still see a double image, similar to how it looks with glasses off. I remember, I ran into this problem years ago but I have totally forgotten about a possible solution...

Any idea?

P.S.: Don't know if that's important but I tested the game on my LG 4K OLED (EDID hack).

Problem solved! With the help of the glorious UE4 Universal Fix, the game looks almost perfect now in 3D Vision!
