Choppy Scrolling in Lion

I formatted the HD and did a brand new Lion install (wish I knew that the Lion recovery would re-download, but oh well), and the scrolling is choppy for me too. I'm on a 15" early 2008 MBP (pre unibody).

For choppy scrolling, try MagicPrefs (free). Been using it ever since magic mice came out and it's helped with performance for those and for trackpads.

I'm having the same choppy scrolling problem with my Magic Mouse on my new MBA after the Lion upgrade. Glad I'm not the only one. It hesitates or doesn't respond at all when I try to scroll. I hope a fix is coming. The trackpad built into my computer works fine.

I'm experiencing it too. I'm on a late 2008 unibody Macbook. If you open up Launchpad and click on a folder (to where it will split the page and show what's inside the folder) you can really notice the choppiness. Scrolling in Safari definitely seems slightly more choppy than it did on Snow Leopard also.

I noticed the other day that when opening the folder in Launchpad it didn't have the same choppiness as I'm getting most of the time, so I'm hopeful that means that a fix will be possible for this.

I have the same choppy scrolling problem with my iMac 2011 on Lion. It works fine if I restart my computer. I have to restart my computer to fix this problem every time. I hope someone can fix this problem.

I have a 2011 mac mini (base model). Having the same issue after waking from sleep with chrome, safari, xcode, BUT finder seems to scroll without any issues...

No scrolling lag after a restart or initial powerup.

Seems like putting the mac to sleep does something...

I'm having this choppy scrolling on my late 2008 iMac 24". It's pretty annoying - don't have it on my 2009 Airbook 11" after upgrading to Lion. The UI is very responsive when swiping to change screen for mission control, but Safari, Mail and iPhoto is a pain in the *****. The scrolling starts with some milliseconds lag. It just doesn't feel right.

Really thinking about getting back to Snow Leopard. The system was very responsive and fast with that OS. But Lion on the iMac causes headaches. Looks like everything runs with the brakes fit.

Do any of you use Safari Plugins like ClickToPlugin or ClickToFlash? I had that installed and after deinstalling it, Safari got a bit smoother, but not as responsive as in Snow Leopard.. Just an idea.

Thanks for the suggestion... I did have clicktoflash installed and removed it. Safari seems to be much more responsive now. Don't know if it's as smooth as on a restart but I can't tell the difference. Still get lag though if i go to some websites (eg apple main page). Don't know what triggers it...

However, other programs like chrome and xcode seem to have the lagging issue still..

Does anybody have this problem in Finder? In my case is all the scrolling fine except horizontal scrolling in Finder when in column view. It happens on both 2010 Macbook Pro and the latest 11" Air. I have just tested on coleagues Macbook Pro 15" bought this week - the same thing.

Interesting is, that the magic mouse scrolls fine in this case. It is only the trackpad that couses problems.

anyone have any more updates or tips for this issue?

seems finder stutters abit when loading mission control for the 1st time after a period of inactivity.... the initial transition graphic seems abit choppy.

Hey pals,

seems like I found a solution for my problem. The choppy scrolling has gone since I deinstalled iStat Menu's from my system.

Do you all have iStat Menus installed?

Then try the following. Open a console and paste the following into the terminal:

cd /Library/Application\ Support\iStat\ local\Uninstaller.app/Contents/MacOS

sudo ./Uninstaller

Enter your password. A dialog box should appear prompting you to uninstall iStat Pro. Click Uninstall.

Enjoy a system that's VERY speedy again.

Good luck!

That's been a false alarm. It was just the reboot - after letting my machine fall asleep and waking it up again everything is very choppy... 😟 So it really has something to do with the sleep mode! Will try hibernate mode...

Good luck everyone else! Hope you'll find something...

im on a mbp 13 2011 2.3 i5 and having exactly the same choppy scrolling, it ruins the lion experience and i regret updating so soon, i can't believe apple didnt discover this in testing - anyway, i just tried a series of things from looking around the net

1) Deleted the dock plist in /Library/Preferences/

2) Deleted the contents of the Caches folder in /Library

3) Reset PRAM (restart + hold cmd, opt, p, r the moment you power on, sounds a second time to confirm)

It was still slower to boot than slow leopard - i would guess 30 seconds, but, once in the entire system was noticably faster - every transition was silky smooth. A lot of preferences get reset but scrolling in safari, itunes, mail, firefox and chrome was absolute faultless (ff and chrome are horrible most the time, safari is hit and miss, mail is generally consistently choppy). It remained silky smooth without exception until i closed the lid, waited for the light to pulse and then reopened, upon which it was back to horrible and choppy. So one way or another sleep in some way plays a part, how im not sure but it totally lost all the good the above steps appeared to do. I don't know if this might shed light on it for anyone else to work out the problem and could be worth a try to see if the above gives you the same results.

Come on apple, this is a major issue that needs sorting immediately - it completely ruins the UX of Lion, right now i would rather be snow leopard, its such a significant thing
