    Hi,
    Just recently I discovered that I have white dots in my videos. Those are really just in accelerated videos. I first noticed it after the most recent updates regarding flashback (Java updates).
    At first I suspected Flash itself, so I uninstalled it. But this did not appear to improve this situation. Anyone else experiencing any problems?

    And where exactly do you experience those white dots? Online videos only or other videos too?

    What other players? Does it also happen in another, even temporarily created, user account?

    I tried a few things, including reseting the PRAM. But I did notice something, first of all it is not limited to video windows. Instead it is simply more apparent on black backgrounds. Secondly it is more sever on the second display (old cinema display) than on the iMac itself.
    Thirdly, after disconnecting and reconnecting the second display it got a little better...
    Other accounts show the same problems..
