    iMac Late 2012 video problem?

    Jean-Paul de Win

      I received my new 27" iMac last week. I've upgraded about everything.


      Today I started working for a project in AE CS6 and was surpised by horizontal lines in the preview during RAM playback.

      It looks like there is some sort of refreshing problem with the screen. I created a similar animation in Premiere to see if it is a global problem, but no errors there (also when playing videos in quicktime full screen there are no problems). On the images you can see the effect.


      When I leave my RAMrender playing, a 'glitch-line' seems to move up every 30 seconds.


      Does anyone have similar problems / experience?
