I like to watch YouTube when playing games, specially the ones that don't require much attention. Since I don't have a second monitor, I do this by using Firefox's Picture-in-Picture while running the games in borderless window/windowed fullscreen. Some recent games that I've played like this with no problem are Crime Scene Cleaners and House Flipper 2.
However, there are a few games where this doesn't seem to work, such as Slay the Spire, Balatro and Noita. For whatever reason, even setting them as borderless, they still act as exclusive fullscreen.
I almost thought this was just a case of poor implementation on their engines, but I very distinctively remember playing like Slay the Spire like that years ago.
For context, my GPU is an AMD 580 with the latest drivers.
