Question / Help Losing game video after alt tabbing.

[Apache7]

When I'm tabbed into the game and start the stream everything is fine until I alt tab to my desktop and back, then I lose my games video input, its just black screen.
Mostly happens with ARMA series games. Both Arma 2 and Arma 3 lose its video output on alt tab.
I've been using OBS for 4-5months now, everything was going smooth until I changed to Windows 8.1 x64 from Win7 x64.
I've also upgraded my GPU right before the switch to Win8.1 but I don't see that causing any issues.

You could try using the Game Capture hotkey functionality and tap it to try and reacquire whenever you lose picture.

I've tried that just now, it didn't work. Once I loose the video output, the only way to restore it is to reload the game.
