Bug Description

Since I installed a clean 13.04 ubuntu on a new computer, I've got the screen set up to automatically turn off after 10 minutes of inactivity, which is the default setting.

However, that shouldn't apply when some application is showing media content in the foreground (e.g. whatching a youtube video), especially when in fullscreen (though actually fullscreen or not shouldn't even matter, provided the application playing media content is on the foreground).

I'm not sure whether this is a regression or has always been sure (i used to have the screen set up to never turn off anyway), but all other operating systems have this right (Windows, Mac OS, Android), at least for the fullscreen case.
Applications playing visual media must inhibit the turning off of the screen (basically playing media should not be considered "inactivity").
Basing the detection of inactivity merely on mouse and keyboard input is ridiculously obsolete.

I don't know whether this is the OS's fault in not allowing applications to inhibit the "idle" state, or if it's the application that is failing to do so. If the latter, then one that doesn't is certainly Google Chrome when playing video.
