I'm having an issue where i'm getting tabbed out as soon as I open Diablo 3 ROS.
It's not crashing, I just end up on my desktop and when I click on the game icon, which is already running, I get a black screen, sometimes even a glimpse of the character select screen and then right back to the desktop.
I usually run the game smoothly without any problems.
I closed any programs that could interfere with the game (steam for example).
NVIDIA Is up to date, couldn't find anything that wasn't.
I even tried to uninstall/reinstall the game, did not change a thing.
You've apparently got something that "steals focus" and minimizes your game.
Something like Fraps can do this (not guaranteed - but it can) - I know that from experience, at least.
What I did, before figuring out that it was Fraps that did it to me (and in some cases, even an old Steam bug from several years ago, where Steam doesn't want to "let go of focus", when starting something..), was the following:
If the game starts minimized, keep clicking the game on your taskbar. Even after the screen goes black, as you're then clicking in the game window.
When clicking fairly fast, you "force focus" onto that program/game, because you are (as mentioned right above), clicking in the game window and forcing whatever it is, to "let go of focus" as it is needed elsewhere.
If it fails; try again (I'm not saying you should keep trying this a hundred times - just 2-3 times - if it doesn't do anything; then that's not the issue you're having).
I know it sounds weird and you probably think I'm trolling you - but I'm not (me saying that, probably didn't help that either.. lol)
That's what I do, if I experience it via Steam - it doesn't happen that often anymore though..
If the above mentioned didn't work - I'm at a loss.
I hope you figure it out though
