Zoom (Accessibility feature) is extremely slow with multiple monitors [OSX 10.10]

Hey - I have a work around. Set the zoom to picture in picture. You can make the picture area full screen if you want. This significantly increases the zoom speed.

Apparently, 10.10.2 fixes it !

I'm using the 10.10.2 developers pre-release and it feels good with Retina + 1080 TV.

Monday I'll test with 3 monitors (retina + 27" Apple Display + 1080 LCD) and let you know.

Yup. Same problem here. Slow on the MBP15" monitor, and intolerable when an external monitor is plugged in. Yosemite was a serious downgrade.

Thanks for reporting, you got my hopes up! Could you please do me a favor and check if this issue has been fixed too: Menu bar icons flash when changing Desktops (namely the icons in the menu bar keeps flashing when ever you switch focus between a Desktop and a Full screen app or between two Desktops, very clearly visible in Dark Mode). Both of these bugs are related to discrete graphics card usage.

Thanks!

Hopefully it fixes it but its still occurring for me on 10.10.1 iMac (27-inch, Late 2012)

Confirmed: 10.10.2 SOLVES THE PROBLEM.

I'm using 3 monitors

- MBP Retina

- Thunderbolt Display 2560x1440

- 1920x1080

Could you please check if this issue has been fixed too: Menu bar icons flash when changing Desktops

In 10.10 and 10.10.1 the icons in the menu bar keeps flashing with white boxes when ever you switch focus between a Desktop and a Full screen app or between two Desktops, very clearly visible in Dark Mode. Does it happen in 10.10.2?

I ask because Apple told me they are directly correlated. Thanks!

Ugh, it's hard to even test this because sometimes it becomes so unresponsive that I just have to reboot the machine.

In my case, I've got a newest generation retina MBP and the problem happens regardless of whether there is a monitor attached.

I thought it might have something to do with the fact that I'm running f.lux to change the screen colors at night. But disabling it doesn't seem to make a difference.

Also, all graphics and window management functions on my system become laggy (though not as bad) after/during running google hangouts.

You will all be happy to know that this is fixed in 10.10.2. YAY!

THE SMOOTHNESS IS REAL

YOSEMITE 10.10.2

Confirmed, 10.10.2 fixes this. Just as good as before! Multiple monitors and all. My only complaint, and I hope Apple hears this minor complaint, is we have been suffering for this from the beginning without any acknowledgment and then they didn't even disclose in the 10.10.2 list of fixes that this item was fixed. I don't understand why but regardless I am DEEPLY grateful to Apple that it is fixed. Thank you.

It did NOT fix the issue for me.

• Yosemite 10.10.2,
• MBP 13 Retina
• 1 external Thunderbolt Display (+own retina)

Extremely slow zoom on the retina screen. And when i shift over to the external 1080p, it's a little smoother but STILL LAGGY.
