Choppy Scrolling in Lion

im reply to your rant lol - neither do i, or about scripts to be honest - and i bought a mac for the same reason, and if im totally honest you should have some concept of how the basics work, if to save your pocket if nothing else - but the only way we know what app causes the problem for Andreas and myself is because he reinstalled Lion, which fixed it, and he noticed that Air Display was no longer installed so suggested it was that - having kept an eye on this thread and having Air Display on my mac i uninstalled it from my system and voila, he was right, and my system is now fine. My problem was with all mouse input devices. It wouldnt have entered my head that a third party app was causing this, especially like when i say, its never been turned on since i upgraded to lion

To figure out which app is causing the problem you would basically uninstall any you suspected might be the problem, which as i mentioned, either rightly or wrongly, could be any apps that provide streaming or server services like air display does seen as that was causing the same issue for us, which is why i listed what apps i have on my machine that runs smoothly, in the hope it would save people like you some time (cos i still suspect its apps to do with streaming or mouse input - at least if your trackpad is playing up) 🙂

just got to play give a little, take a little if you want a solution quickly, as 10.7.1 just came out and didnt fix your problem, its safe to bet that 10.7.2 wont be out for a little while so its a case of wait and get annoyed or do a little digging and at least fail from trying. Its not likely your going to break anything at least, i love that about macs and their install/uninstall model 😀

if you haven't already TJ, try deleting these files:

User/Library(which is invisible now)/Preferences/

com.apple.driver.AppleBluetoothMultitouch.mouse.plist

com.apple.driver.AppleBluetoothMultitouch.mouse.plist.lockfile

com.apple.driver.AppleHIDMouse.plist

and do a reset

i found this on another forum a while back - it didn't work for me as my issue was trackpad as well (and overall, down to Air Display) - apparently some settings in SL didnt get carried over to Lion, meaning they cause problems in the config - deleting them should rebuild i think and might sort it. Im not sure how true that is but it doesnt do any harm trying

you could try these other things ive seen about as well

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

2) Delete 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)

although i would save the dock plist for last ditch, simply because it resets a whole lot of preferences

I'm experiencing choppy scrolling in Lion on my early 2008 iMac. Is anyone else experiencing this? Any remedies?

I also own an 11-inch Macbook Air and the scrolling seems better on that machine.

Does it depend on the browser your using? For me, scrolling with Safari is fine on Lion.

I noticed Opera is choppy when scrolling in Lion.

Hi,

_bast, I tried several but not all of your tipps and they didn't help. What I did was:

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

2) Reset PRAM

3) Deleted some obsolete entries in /Library/StartupItems

Will try the deletion of

com.apple.driver.AppleBluetoothMultitouch.mouse.plist

com.apple.driver.AppleBluetoothMultitouch.mouse.plist.lockfile

com.apple.driver.AppleHIDMouse.plist

this evening. Installing 10.7.1 didn't help. Repairing file permissions and verifying disk didn't help.

Does anybody see his/hers problems resolved after all?

Hi all,

had the same issue on my new macbook air 2011. I managed to resolve it by removing an application called DisplayPad, which is an application that allows my iPad to be used as a second monitor.

I hope some more peolpe may be helped with this information.

Hey guys,

today I phoned Apple support and lo and behold, the technician found a solution to my problem! I simply had to create a new user account and the laggy scrolling was all gone.

Now all I have to do is copy all documents and settings, backups of apps and stuff to /Users/Shared and move them to the new account.

I had no AirDisplay or DisplayPad installed, so that was not my problem.

I'm going to post my experience with this move to a new account...

Hope this helps.

when i received new 2011 MBA the scrolling was fine. Now I had to erase disk and reinstall Lion and scrolling seems worse, especially in app store.

My System: MacBook Pro 13in (Mid-2009)/8GB ram/500GB HD (360GB free)/2.26Ghz Core 2 Duo/Lion 10.7.1

I've experienced the choppy/laggy scrolling problem systemwide since installing OS X Lion. It seemed to worsen after the update (10.7.1).

** Since installing Lion "kernel_task" also consistently uses 450-650MB ram, though the two issues aren't necessarily related.

I don't only experience the scrolling problem in Safari or browers, as many are reporting; I experience it systemwide: browsers (chrome, safari, firefox), desktop, finder, applications folder, iTunes, Word, App Store, Preview, Sparrow, iCal.

I followed several tips given in this discussion and on forum.macrumors discussions, including: memtest (ok), verify/repair disk permissions (ok), verify/repair disk (ok), clear font cache using FontNuke (ok), delete all system/user caches using iTweaX (ok), exclude HD from spotlight indexing (ok), reinstall Lion from Recovery HD (ok).

Together, these steps seemed to improve performance somewhat, but did not cure the problem.

Finally I uninstalled/deleted all traces of Adobe from my computer, including some remnants of CS4, Flash Player and AIR. This eliminated the choppy/laggy scrolling problem immediately. Navigation systemwide became smooth and fast.

However, I reinstalled Flash this morning and the problem returned instantly.

Hey I also have the same problem with a 2007 MacBook Pro 2.2GHz...

Furthermore when i leave 2 fingers on the trackpad (not moving), the scrolling goes crazy up and down randomly...

I think this is the problem?

I found what is causing this choppy scroll problem on my MacBook Air 11'' i7 : SLEEP MODE.

Actually If I reboot the mac and open a web browser (Safari or Chrome, doesn't matter) and scroll through a long page, it's smooth and sleek. Then I close the lid, wait 30 seconds and reopen the lid. I am back on the browser but the scrolling has nothing to do with the smoothness before entering sleep, it is now choppy and ugly ! Tried this with a brand new user created on purpose, absolutely the same problem !

Thanks. I will disable Sleep Mode and report back with results.

Disabled Sleep Mode and my system is still choppy/laggy immediately after 2 fresh restarts.

I mentioned in an earlier post that uninstalling Flash appeared to solve the problem. However, this has not worked in subsequent attempts.

Problem persists with Sleep Mode disabled, Spotlight disabled, Flash uninstalled.

There's the page, and if you don't happen to find the specific item to give feedback about, choose your type of computer and just add a note "putting here, as don't see specific item to give feedback on" etc.

Hey guys!

I've found a second thing that is causing choppy scrolling of windows and window content: It's the blurring effects that are present all around Lion. I experienced very bad scrolling and overall performance when I had Terminal windows open on the same screen as Safari windows. After I disabled the blur effect in the background color of the Terminal window, the speed was back to normal. Everything fine.

I'm still fighting with some blurring effects in Dock->Stacks - opening the Stack with many items in it takes ages.. I mean it's very slow and choppy.

I've also still my iTunes skipping issue - CPU is not doing much, but iTunes skips while browsing heavily in Safari or in Aperture.

So if Apple could give us an option to disable blurring some of the worst problems would go away.

Hello!

Just wanted to say that my choppy scrolling problem has appeared again. Don't know what is causing it, but neither a new user nor disabling blurry backgrounds in Terminal windows does change that. I also upgraded my iMac to 6 GB. Scrolling is all fine after a reboot and terrible after putting the Mac to sleep and waking it up again.

Scrolling stays ugly and choppy even after minutes of use and doesn't go away. Only a restart seems to solve this issue.

Anybody else still experiencing this?
