Random flashing/blinking pixels on screen, according to image color

Hello! I have my macbook pro for like 3 months, and I am pretty much loving it.

However, I now realized that depending on the color of the image I am seeing on my HiRes led screen, a lot of pixels start to flash/blink (don't know the right word) randomly. I mean, it is totally random, they just go crazy! It's not like they are defective (I THINK/HOPE), they are displaying the right color, then get white, then display the right color again - All at random. And it is not always the same pixels.

Actually, someone who does not know that this happens, do not realize it is happening. It is very hard to note that when seeing from like 40cms from the screen. But now that I realized that, I can't not see it anymore! And it is pretty distracting. It happens only when I am seeing images with light grey or blue colors.

Is this normal? I do not know if it was like that since I bought my macbook, because I realized this happens just now.. And now I can't stop seeing them! They haunt me! lol


So.. Is this normal? Is there anything I can do about it?

Thanks very much!

 

Someone?

 

Probably defective, I'd return it.
