    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
