Hi Gary,

was that with the same rootfs ?
Did you calibrate again after flashing this one ?

that's what I also got and put in the comit message :

commit f8852824e6944943480f685d498ccce4ffec2c30
Date:   Mon Oct 7 15:37:29 2013 +0000

    qtbase: update mx5 & mx6 support
   =20
    - remove 5.0.2 as meta-qt5 has 5.1.0 by default
    - tested on i.MX53 with eglfs and xcb platforms. FPS is not very
    good despite the GPU (~24 fps on 800x480)
    - tested on i.MX6 with eglfs platform : performance is very good
    (> 150 fps on 640x480)
