    Can someone post a video of their UI "lag"? It's difficult to imagine the extent of it from the descriptions.

    Also plz post your processor speed with the video!

    That was my experience with 2 of them! A few others have posted similar results. In store I was able to create the same problem with just 2 tabs, 1 of them being youtube and a few spaces.

    I'm surprised I haven't seen more people talking about issues like this.

    I guess I'll have to wait and see when mine arrives. I think I would be pretty annoyed if it lagged like it did in your video. Does it always happen or just a few times a day?

    I got the same kinda lag on a 2013 13.3. The lag between spaces happens if your don't fully swipe. I don't have that kinda lag on my base model 12.

    It didn't happen all of the time, but the UI lag was pretty bad. I use spaces all day long, so I noticed it to the point it needed to be returned. I actually ended up just getting an 11" air b.c it is buttery smooth. Yes, the screen is nowhere near as good, but I usually am docked to an external monitor.

    I ordered a second macbook just in case the first one was defective. That video is of the second one.

    I usually stick to one space and don't use Mission Control so much since I'm used to using control + tab or clicking on dock icons. Do you think I would notice this elsewhere?

    Even if I don't, I don't know if I'd keep a laptop that lags that much from just switching between spaces.

    you wouldn't notice it doing what you said above, but just knowing it happens drove me crazy.

    Yeah I feel like that might drive me crazy too. I've been waiting since the 10th for my pre-order and it still hasn't shipped. I really do hope I don't experience this on my 1.3 GHz but this seems like a GPU issue. I guess I'll have to wait and see.

    Thanks for the feedback.

    The MacBook airs screen drove me crazy. I can deal with minimal ui lag for a better screen.

    I usually use a couple of spaces and a few full screen apps. I don't see any lag like that at all. I don't know why you are seeing that.

    Mine does that, and I think I mentioned that it didn't because I wasn't sure what someone was talking about.

    This is a bug with Yosemite that was introduced with 10.10.2. It happens on my 2012 MacBook Air 13" 2.0 GHz Core i7 and my 2012 27" iMac 3.4 GHz Core i7.

    I don't think this is specific to the Retina MacBook.

    Video of UI lag?


    Yeah, that was probably me; I asked about UI lag. However, that is an interesting observation you mention- that this could be an issue with Yosemite as opposed to the hardware. You say this was introduced in 10.10.2 but does it still surface in 10.10.3?(which is what I assume you and mattopotamus are using)

    That's because your average user doesn't buy a core m powered macbook and sit there opening 8 spaces while swiping frantically thru them. These are people intentionally trying to choke a machine. im not sure why anyone would ever NEED that many spaces running at once but I'm sure they would be wise enough to buy a rMBP.

    maybe you should send them the video (http://bugreport.apple.com), specifying them that it's on the new macbook.

    they usually take a few days to read the reports that are submitted.

    Yes, all of my computers were updated to 10.10.3. It may have started in 10.10.1, but I think it was .2.

    It's very annoying when it does it. The fact that it does it on multiple computers points to a software bug.

    How much time do you *really* spend switching between apps?

    Trying to put "lag-gate" into perspective here.

    How much time do you really spend doing things that *may* demonstrate a bit of UI lag, compared to actually interacting with your applications, or just reading stuff on the screen?

    I would be surprised if anyone spent more than 1% of their total usage switching between apps, brower tabs, running mission control, launhpad, swiping between desktops etc.

    I might typically open an app, such as MS Word or Safari, interact with it for 5 mintues, then switch to another app, e.g. Mail or Calendar to check something. I normally do this with Ctrl-Tab. Even assuming I switch apps by swiping between desktops, I doubt I do this more than once every 5 minutes, if that. Even if you are doing a massive amount of cut & paste between desktops, you're unlikely to do this more than once every 30 seconds.

    How long does the UI change take compared to the usage time? 4% max?

    So if you would rather look at an inferior (MBA) screen for 96% of the time, instead of having a marginally less fluid UI transistion for the remaining 4% of the time, then I respectfully suggest you have your priorities wrong.

    If your switching frequency is greater than 4% of the total time, then you need to improve your focus & concentration on the task at hand, because you're wasting a lot of time with context switching!

    Seriously? I think anytime when software or hardware doesn't operate as it should, knocking the person who points out the flaw and telling them their priorities are out of whack is in poor form. To some it might be a trivial nuisance, whereas it might be more disruptive to others. Its like someone telling another what they should eat (and like it).

    ----------

    Yeah, if the behavior is being exhibited on multiple models since 10.10.2, if would certainly qualify as a software bug. I don't use Spaces myself, but a professional reviewer noted last week that anything "transition based" animation on the MacBook caused some occasional lags (Mission control stuff).

    This is why is "respectfully" suggested that someone (as suggested) who would choose the MBA over the rMB purely because of the screen might be making a mistake.

    My reason? Because, as has also been suggested, it is possible that the UI lag is a software issue that will hopefully be resolved in a couple of months. I wouldn't want someone to forego the pleasure of the better screen, because of a temporary irritation.

    I'm sure that the UI lag, for those who perceive it (many don't notice it), detracts from the pleasure of ownership. But I also think that such defects need to be put into into perspective, hence my analysis of "usage time vs UI-lag time".

    It's a bit like rejecting a car that has fantastic handling and fuel economy because the electric windows are too slow - it misses the point.

    But some people just get more wound-up by small irritations than others. Fair enough - I can't stand people who eat noisily with their mouths open. It's puts me off my own meal, however tasty it is! So we all have our foibles :)

    With current tech, you can either have perfect screen with lag (rMB) oraz perfect animations with inferior screen (MBA). It's up to you as a customer to choose what is important to you and which one suits your needs. Simple as that.

    Reason behind UI perfromance is really simple, it is not that GPU on rMB is so slow it coudln't handle simple moving windows with some transparency - but with standard operational scenario, and by standard I mean reading facebook and macrumors :) , having some text processing and Spotify open, GPU is in low-power state, so we can have that all hours of battery life. Doing some stuff that requires raw processing power like fast animations does not properly put GPU to its potenatial speed fast enough, so you may experience some lag in the process.

    It will surely be fixed someday, with better power switching from Intel and better software management of power states on Apple side, but I doubt it is either a high priority or going to happen any time soon. Expect some fixes in next harware and software iterations ;)
