Question / Help [FIX] Modern Warfare Crashes Alt+Tab w/ OBS in BG

So to clear up the title:
Modern Warfare is crashing whenever I Alt+Tab with OBS in the background.
The game will boot and play normally with OBS in the background, it will also record normally; but it will crash when attempting to alt+tab with OBS in the background.

I'm perfectly able to alt+tab Modern Warfare when OBS is NOT running.

So, can anyone help me out with this and what the culprit may be? I'm guessing it's the game itself having some issue but I figured I'd ask here if anyone else is having the same issue.

From a recent update, this ‘fix’ seemed to have stopped working.

I was having this issue a few days ago again. I sent in a report to Activision support so I can only hope they look it over.

If they’re not, try updating your graphics card drivers, this *seems* to have helped with this issue.

As an experiment which I haven’t tried yet. It might be best to open the game in windowed mode, sometimes it does this automatically when you’re interacting with another window during launch.
Then change it back to fullscreen before queueing for a game.
This *might* trick the game to allowing alt+tab without crashing.
Again, I haven’t been able to test this.

Run the game in windowed mode extended instead of fullscreen or windowed fullscreen. Solved my issues. Zero game crashes and zero frame drop/crash in OBS.
