I have been having an issue where any game I play with plutonium randomly tabs to my desktop screen. The game does not crash, nor do I get kicked out of a match. I am able to go right back into the game in a good five seconds or so and then continue like normal, but it does get annoying when I go down in zombies or get killed in multiplayer because of it.
Also, there is no error screen or anything telling me what the problem is. That is where most of my confusion comes from.
