Accessibility zoom jerky in Yosemite

Under Accessibility in System Preferences, you can set up to zoom using your mouse's scroll wheel and the control key (default). This allow quick and smooth zooms in and out of your desktop to see smaller text or features. It worked seamlessly until I upgraded to Yosemite. Now the motion is jerky and a swipe takes seconds to complete the zoom. And moving the cursor is jerky when zoomed in, too. Is anyone else seeing this problem?

The 10.10.1 update just released today does appear to show some improvements for graphics performance, although performance still seems better with "Reduce transparency" checked. Perhaps this will help others, too. At least it seems that Apple is listening, aware of the problem, and trying to find a solution.

Same issue. And always there is someone saying to reboot, reset SMS, clear PRAM, use last updates.

Using a MBP 13" Retina with Yosemite with two external displays pushing 1080p. In Mavericks everythings was just fine.

What worked for me was ...

Activating and deactivating "Smooth images" (that was crazzy). What is more crazzy is that zoom with smooth works much better, but I do not want that feature (I am a user interface developer, I need zoom to see how pages are rendered, pixel-by-pixel)

And the best temporary kludge was...

Setup "Zoom Style" to "Picture-in-picture" and then in "More Options…", "Adjust Size and Location" set the best lens size . I resized it to th size of my entire screen, but it is a bit slow; better setup half of the screen size.

I hope it helps, and I hope dunnb Apple developers pay more attention to details next time. I swear the zoom was the best feature of MacOSX for me.

If you haven't yet installed the 10.10.2 update that was released this week, I highly encourage that you do. Since installing it, I no longer have any problems with zoom (even after turning transparency back on) and have experienced no further Wi-Fi disconnects (which were occurring several times a day on 10.10.1).

Glad these issues are finally fixed but I am still disappointed that it took Apple 3 months to find and fix things that should never have been broken in the first place. I was also disappointed that Apple even stopped responding to my e-mails to my assigned support technician (last response was Nov 7 despite continued detailed feedback trying to isolate the problems), even though I am a paid AppleCare customer.

Yay! Great. I was using the "window in window" version in the meanwhile, and relying on the <+> key for certain applications like Safari. This is much better. Thanks for calling my (our) attention to this improvement.

(This feature is activated in the Accessibility pref pane in System Preferences, thusly:
