Extreme mouse cursor lag when using Accessibility Zoom (Fullscreen) in Yosemite
I have a Retina MacBook Pro running OS X Yosemite (10.10), clean installed, connected to an external Thunderbolt Display. When I zoom in using Accessibility, I experience a very prominent lag, moving my mouse cursor (either with my Magic Mouse or Magic Trackpad or the built-in Trackpad) around or when zooming out. It is especially visible when zoomed in on applications like Calendar and Mail. This never happened in Mavericks. My settings are as follows.
I've tried creating a new user account on my Mac and the problem still persists, which leads me to believe it's a bug with Yosemite.
Anyone else have the same problem?
