Choppy graphics since Thunderbolt-Update

I have not noticed this on my i7 11".

I have noticed the same problem. I reformatted thinking it could have been something else, but as soon as I installed the thunderbolt update, I had the same problem. I'm very surprised this passed Apple's QA, since it is so noticeable. I'm probably going to reformat again and not install the update until this issue is fixed.

i wonder if you can post a video and steps to reproduce it. im not seeing anything here so that might be helpful

I have the exact problem and I made a thread about it and did what others recommended but it's still the same.

I really hope Apple fixes it in future updates

I don't suppose you could do a video capture of this using the QuickTime Player application? To do a video screen capture first set up the action you want to capture, launch QuickTime Player, go to the File menu and select New Screen Recording. Start the recording with the red button, do the actions needed to reproduce the issue, record it then click the button again to stop. Save the resulting video file to your desktop.

You can post the video here using the Insert video button when replying to a post.

It was the display driver that was in the Thunderbolt update. Original/stock Lion 10.7 has driver 7.0.6. This works beautifully - MC animations smooth, browser scrolling fluid - in other words what you would expect from a $1200 laptop 🙂 I pulled the trigger and did a Command-R 'reinstall' which put the original driver back on.

The TB update moved the driver to 7.0.8 and some folks are running 10.7.2 (beta ?) and it's driver is at 7.1.2. So far - folks are reporting that all of these new drivers still have the choppiness 😟

To find out what driver is on your system, run this in a terminal:

kextstat | egrep 'Intel.*Graphics'

You shoud get something like below. The number inside the parens is the driver version.

71 0 0xffffff7f815e4000 0x2c000 0x2c000 com.apple.driver.AppleIntelSNBGraphicsFB (7.0.6) <70 9 8 7 6 5 4 3 1>

73 0 0xffffff7f8161e000 0xe1000 0xe1000 com.apple.driver.AppleIntelHDGraphics (7.0.6) <72 70 9 7 5 4 3 1>

So the real question - how can we escelate this with Apple ? This is a regression and user experience impact on a brand new line/model (MBA).

You need to get on the phone with AppleCare and report the issue. You'll most likely need to get past the Tier 1 agent as well, this isn't something they handle.

I did and they did. However they claimed they could not reproduce and closed. 😟

However - it seems the update is not available anymore from Software Update. Hopefully this is intentional and a good sign.
