Resolved [VIDEO] Screen Flashing - Is anyone else experiencing this?

[Hustler1337]

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:

[] Flash screen at warning signal
-> Test Screenflash

That covers it all really. Could be Mavericks issue, or just coincidence and it's a faulty GPU that's just slowly crapping out.

I experience it occasionally when using discrete graphics.

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?

YMW! Glad to be of help.
