    Hi guys,

    I'm running OS X Mavericks on my 2011 MacBook Pro. For about the last month or so, i've noticed an odd behaviour - my whole screen flashes at random times, though more recently, I've noticed that it flashes during certain behaviour.

    When I have the Twitter app for Mac OS open and click on any number buttons or letters, the screen seems to flash. I've uploaded a quick video on Youtube to show what happens: http://youtu.be/v9DY9FMntSQ

    I've also noticed this happen when I have the UTorrent app open - when the download completes and a growl notification is displayed on the top right of the screen to say that a download is complete, the screen also flashes.

    Does anyone have any idea on what is going on? I am seriously hoping that this is not a graphics card problem (after hearing of the common faulty graphics cards across the 2011 MBP line, i've been getting very paranoid) but rather something to do with OS X Mavericks instead or software related (which I can live with).

    Would appreciate any help and advice.

    Thank you! ;)

    The same here when using not binded keys in GarageBand. A beep sound and a flash. You can adjust this in prefs pane:

    OMG THANK YOU BDM STUDIOS NL !!!!!!!:):):):)

    This looks to have solved the problem. Mine was already unchecked but I re-checked the option and then unchecked it. Seems to have stopped the flashing issue. Had to translate the screenshot with Google Translate :)

    Now I can finally use my MBP without being irritated by annoying screen flashes. Thanks once again! ;)

    Tinkering can work sometimes.

    Perhaps it's time for me to change my OS to English version? :D

    YMW! Glad to be of help.

    Cheers
