Choppy/zig-zagging movement on zoomed-in image?

Nov 12, 2012 10:16 PM

1-week-old MacBook Pro - Non-Retina - OSX 10.8.2 / 2.6GHz Intel Core i7 / 8GB RAM / 750GB HD (currently 522GB free space)


I initially discovered my issue in Photoshop CS6, but just installed the trial of LR 4.2, as well as 4.3RC, to see if the problem persisted, and it does.  My problem is choppy/zig-zagging movement when moving around (two-fingered scrolling using my trackpad) on a zoomed-in image.  Here's a video capture of the problem in Photoshop - and it does the exact same thing in LR.  I did post yesterday in the Photoshop forum but didn't get any advice other than to use a mouse instead of a helpful.   The image in this video is just a jpg, quite small in file size.



I have adjusted every single scrolling/trackpad option in System Preferences, tried enabling and disabling automatic graphics switching in Energy Saver Preferences, changed all Performance Preferences in PS.  I've also installed all Apple and Adobe updates.  I'm only posting here due to the lack of response in the Photoshop forum, and since the problem appeared in LR, as well.  I brought my computer into Apple yesterday as well, and the "genius" that helped me didn't think that the problem was a hardware/Apple issue, but Adobe-related instead.  Have any of you experienced this?  Thanks in advance for any insight you may have!

    I have never seen anything like this at all.  I also would try this with a mouse and see if it is related to the trackpad.  A good resource for help from Adobe is to use the Adobe Customer Care page on Twitter.  Those guys are amazingly fast to respond and have been a super help to me a few times in the past.  If anyone can help, it is them.
