Q: New iMac 27inch screen flickering/tearing/shutoff

I have been experiencing some problems with the all new iMac 27inch display.
At non-fixed intervals i will get one of the following:

Screen distortion/flicker somewhere random in the screen (feels like it is more in the lower part) that looks like a horizontal bar of about 2-3inches just popping in and out of the screen.

Screen will go completely black for a second and then come back on. Sometimes 2-3 times in a row.

Somebody else already made some video-clips about these problems, I am experiencing exactly the same behaviour.

Just to not that in the course of writing this post my screen has flickered 13 times and has gone black 2 times.

iMac 27inch 3Ghz 4GB 1TB ATI 4670, Mac OS X (10.6.1)

    I thought I had noticed this just after the update. Mine is a week 46 and has been fine since purchase and to be honest is fine now.

    One thing I have noticed - I opened Automator and watched the quicktime video which, by the way was terrible to listen too. However, the colour a light grey background when watched flickers very gradually(bottom right of the window) - this might be my eyes? but I have found the screen to be less responsive.

    Can someone try the video and let me know if they see the same?

    You might want to turn the volume down
