    No, that's not what it means. Lag in this context most probably means the amount of time it takes for the image to show up on the screen after it's been rendered.

    You could, for example, have 10,000 FPS in glxgears and still have it display on your screen a second late. That's what it means.

      I don't. My post wasn't pro or against Mir, just about licenses and copyright.
      I'm personally fine with any project having any license it wishes, it's not like anyone forces anybody to contribute.

        True, it is a term used widely on the gaming world to indicate that network data transportation/latency is out of sync or behind what it should be.

        On this case we are talking about graphical lag, how can you notice the underlying system is lagging or behind by 1 second without a tool to measure it? Which part on the video showing XMir running the desktop environments we see the mouse pointer or some other component stop responding for 1 second?

        In any case here is the video which some guys are saying has a 1 second lag (also some one else said 30% fps drop means 1 second lag).

        On a side note: maybe the guy that said he saw 1 second lag didn't noticed that what lagged was his flash player

          A bit off-topic, but it really bothers me how Michael stopped maintaining custom user titles. You don't have any, other important people don't have any, some have wrong or outdated titles, etc. It makes it hard to know who is who.

            I just noticed something that might come as a lag if you assume a mouse gesture is used. When blender is opened in Unity and it zooms in and out, one second before that happens the pointer goes down. I think whoever said there was lag assumed that the pointer going down was a mouse gesture to zoom in, while it's probably done with the scroll wheel, and such order might have been given after the pointer went down.
            Otherwise, I have no idea how can he know of any lag, since he doesn't see when the input is done.

            Even when you are right about it, and .dee is wrong in his statement that "it's designed for Unity" (is true for Mir, but it's running on XMir, and X wasn't designed with Unity in mind), they better take it out of alpha fast, since they expect it to be in production use (which means it need to go through beta and realease candidates) in 13.10. Also, is not a valid excuse to run a desktop on XMir. Mir might have benefits. XMir have them for particular apps. XMir doesn't provide none of those when running all of your desktop on it. And as all software, it's bug surface, and you are making that bigger by putting an unneeded, non-feature providing, extra layer.
