I only notice it when I'm playing games, but it could be going on at other times. I'll be playing my game, and I press a button on my keyboard for the game but it makes a ding that it isn't a valid input and I see it's unselected the game I'm playing. With a few games I'll be playing and the menu automatically opens up and my mouse icon is suddenly on a different monitor than it was a moment ago (I use 3 monitors, the middle one being the one I display my game. It mostly goes to my right monitor) and to continue playing my game I have to manually move the mouse and reselect the game.
I have McAfee and just scanned and it says I don't have any viruses or any issues, what else could it be? It's been going on for about a month now. It's not necessarily making it so I can't do things, but as I stream game play occasionally, it is frustrating
Edit to ad: I don't believe I've downloaded anything new since it's started. If anything, I Streamlabs OBS tries to update every time I open it but McAfee doesn't let it so it just launches without being updated
