This is mainly an issue if you are running windowed or borderless windowed games and under Windows there is latency too.

It is a shame that playing a game on a window is given such a low priority as personally i often prefer to do that for short term sessions where i'm waiting for something (email, some task or just pass time). Though under Windows with how busy the desktop environment often is it can be distracting. But on Linux, especially with a tiled window manager where you can have a tiny status bar above/below the window and perhaps a stripe here or there with stuff, it is perfectly normal to want to play a game in a window as opposed to fullscreen.
