    I thought this deserved it's own thread.

    Whatever they did has completely fixed the scrolling lag for me on image heavy websites.

    I really like Safari, but I love Chrome. I hope that it eventually moves to implement this solution also.

    Credit goes to bill-p, he's the one who made me discover this.

    The only time I have noticed scrolling lag is on The Verge. I tried the webkit and scrolling lag was now non existent. Though, it's not a big issue for me as it is for others so I'll keep on using safari.

    Safari was pretty flawless outside of Facebook for me, but this makes even FB run at 30FPS+ thanks :D

    Now lets hope they can remove the odd jutters that occur with 10.9!

    just saw this in another thread. its AMAZING. It makes this machine much more useable. Sites like the verge, and engadget lagged a ton, and now its smooth as butter

    disable smooth scrolling, watch scroll lag disappear

    I'm not a fan of the Webkit solution in its current state. It actually slows OSX down and that lag remains even after you quit the browser. It's noticeable to the naked eye. Just run a few benchmarks and you'll see what I mean. Unigine and cinebench both yield significantly lower FPS after running the webkit. You need to reboot or log out in order to get rid of the lag. I think I'll pass until it's ready for prime time. Promising but not quite yet there.

    That's due to memory leak bugs, report them!

    I don't understand you people. What is this "scrolling lag" you're talking about?

    I've had this RMBP since their launch and have NEVER experienced "scrolling lag".

    Me neither. Apparently only a few users found this on their machines. The same with the many others issues stated here on the forum.

    I've checked in 2 macstores and every single rMBP had this issue at the same level. If you think it's not there, you either visit only websites with simple layout or you don't know what 'real smoothiness' means ;)

    it means you have absolutely no idea what lag is. good for you, but not for the rest of us.

    I actually notice scroll lag, but just while visiting Facebook. Every other sites works fine without any sort of lag. And I am quite happpy with my rMBP.:apple:

    I also have checked in a few rMBP, not just mine and it doesn't appear in any of them. Or maybe we are all wrong here and you have the right call. Because you also checked my machine and the ones I tested here right?

    Just wondering. ;)

    Having used Quartz Debug on both of these it does seem that CPU usage is around 30% higher which looks to (hopefully) suggest that multicore processing is being used.

    I notice still some lag with scrolling twitter quickly and the top section of The Verge does also seem to slow right down; Facebook however is silky smooth. Finally.

    Use Safari in full screen.

    Visit the NY Times :

    Click on any article.

    Double-tap to zoom (don't use the text-zoom buttons).

    Scroll up and down quickly (two finger scroll).

    Watch Safari trod through molasses.

    If that doesn't do it for you on your rMBP, then I simply don't know what to say...

    And I almost thought it was common for people who try WebKit nightly often (to check for new HTML5 features implemented or fixes to current layout issues).

    Now, if only Apple would implement the same fix across all OSX views so that other apps can take advantage of it as well.
