Just as the title says. If I leave xoutput running and I go play a game that uses mouse, the mouse input will experience a short interruption to its tracking, and maybe button presses too, but that would be too hard to test. The interruptions occur every few seconds, and it's only noticeable if you're moving the mouse when it occurs. For example, in Overwatch I noticed that my mouse-look was having tiny instances where the movement stopped. Just enough to throw off aim tracking and enough to completely ruin a flick shot if it happens right at that moment.
