    Hi Folks:

    there i am with a spanking new MacPro 2013 Quad and 2x D700s (came today w/ 10.9.4 on it) and i set it up and updated it to 10.9.5 right away.

    But now i am experiencing screen jitter (moving Windows and flying over the Dock with the mouse produces jitter/lagging of Window and Dock Icons)

    Running a LG 34UM95-P Thunderbolt 2 Display at 60 Hertz (NTSC) / Resolution = best for Display (is equal 3440 x 1440) and havent had that before when a Early 2011 MBP 17" was driving the same display on 10.9.4.

    Anyone else having/seeing this problem/bug after installing 10.9.5?

    Thank you,

    Yes, I'm seeing similar problems intermittently. Started about 24 hours after updating to 10.9.5. MacPro 2013 6 core D500

    i don´t think that we are the only ones experiencing this..

    have contacted APPL Support on this - they will get back to me tomorrow..

    btw: have you gotten the normal iTunes that came with 10.9.5?
