Safari jitters when scrolling

Presumably the 1st developer preview, in which case it's weird it wasn't fixed (unless not enough developers reported it).

It probably won't be long before an initial patch is ready, as Apple are usually already working on it before release, with all the stuff they wanted to fix but ran out of time to. If you want to make sure they get a move on, and you have a developer account, then make sure to head over to bugreport.apple.com to report the issue, as more reports should hopefully mean a greater priority.

Since upgrading to mavericks I notice that when scrolling up or down on the trackpad in a webpage shakes the screen left or right. I turned off gestures to swipe to back page and no help. Anyone else notice this?

I'm getting exactly the same problem, its very irritating!

seems they changed the calibration or something!
 
I've been getting jittery scrolling on sites like Joystiq.com. I wonder if it has to do with Adblock.
 
Seems that I have something wrong with my eyes. This new "feature" which works like iOS and Android in apps that support "drag to update" is really annoying in OSX. Fonts take longer to smooth causing a weird visual effect. I tried disable every font smoothing possible setting but none of them worked.

Hopefully they'll fix this before the next beach-named OSX.
 
Disabling "Swipe between pages" in System Preferences/Mouse (or Trackpad i guess) seems to reduce the jitter for me (but therefore also disables the left/right scrolling).

Is this what you are referring to or is this something else?
 
I have noticed this problem as well. Seems to be particularly annoying when scrolling over an embedded window with horizontal scroll.
 
My wife and I both have Airs and have upgraded to Mavericks over the last few days.

Both of us are experiencing the jittery scroll.

It's mild on Safari and Chrome, worse on Firefox - and terrible within Outlook.

She spends a lot of time in Outlook and is sorry she upgraded.

I think Apple tried to solve some annoyance seen in retina Macbooks, but that messed with non-retina ones.

Unfortunately it didn't make any difference for me.:(
 
Noticed that in GM seeds on my 15' rMBP (2012 model). The trackpad is more sensitive to respond to smaller touch events. It was damper in ML.

In both Safari and Chrome, the page scroll tends to be jerky when fingers stop moving.
 
If its down to the track pad sensitivity couldn't apple give us some sensitivity settings in system preferences.

I've got a non-retina macbook (MBA 2013), absolutely no scroll 'jittering" here. butter smooth on every site in safari. Don't appear to have any issues with chrome either.

Apple have just released Mavericks 10.9.1 and has fixed the scrolling problem for me on my late 2011 macbook pro.:)
 
I installed 10.9.1 but the issue remains on my Late 2013 rMPB. This issue effects both Safari and Chrome. I've been using FireFox as a work around but it's definitely not my browser of choice. I've been searching the web high and low for a fix with no luck. Hopefully someone can come to the rescue because it drives me nuts!
 
Same here, on 10.9.1. Not only that, but if you do the trackpad gesture to hide all windows (to the edge of the screen), it will actually follow your trackpad movements to the exact position. It's a bit hard to explain, but if, for example, you do the 3-finger spread gesture to show the desktop, keep the fingers depressed on the trackpad, and "pause" the effect mid-air, it will actually "freeze" the windows in the middle of the spreading animation, then you would either scroll back down or continue to spread the windows. When doing this, the windows kind of jiggle and shake a bit. It's a bit similar to doing the home screen 4-finger swipe animation on the iPad - if you keep the fingers on the screen while swiping in, the windows will stay with your fingers. It's fine on the iPad, but annoying on my computer, because the windows look all... weird, and the jiggling effect is also very annoying. This is new to Mavericks, because I tested this on Mountain Lion, and spreading windows didn't stay with your fingers, it would spread quickly right away. It's the same thing with swiping in for the Launchpad - the animation goes slowly/choppily, like it's waiting for your fingers. Again, very hard to explain - you have to try it for yourself.

Other little things - most areas within the OS are now horizontally scroll-able. For example, when going to the Migration Assistant and selecting the specific backup to restore from, you can scroll it up and down, as well as side to side. Kind of cheesy and annoying, and very iOS-like. Unnecessary on a computer, IMHO.

I know, I'm very details-oriented, but hope my insight helps. I'm afraid a bug report would just default to Apple saying this is the intended behavior, but it's just so... buggy as it is. I really liked ML's implementation better; it felt properly "computer-like" while offering gesture support, but Mavericks feels too... iPad-like.
