Okay, this seems to happen only when i'm playing some sort of game in windowed mode. Say I want to play Grand Theft Auto 5 in windowed borderless and every time I click, a new window pops up titled "Microsoft Windows" and instantly closes. It will open and close instantly. It becomes very annoying because it takes control as the primary window and makes me not be able to click on the bottom of the screen because of the taskbar getting in the way, the screen will flash out of the window instantly because of this. This doesn't happen in things like chrome for some reason. I don't know what to do because i don't know whats causing it, I've run scans on malwarebytes and Avast and both came up empty. Any help would be greatly appreciated.
