I was in a middle of playing a game using PPSSPP in fullscreen when a window appeared saying that it recommends me to donate to Tixati to help its development, blocking most of the screen. I don't mind the notification, it's just that I think it shouldn't steal focus from another application like that, moreover a fullscreen application. I almost died, eaten by a monster!

Joke aside, I don't know if this also happens to other fullscreen applications because this is the first time the window ever showed itself when I'm running an application in fullscreen.

Cheers.
