I don't even know how to explain that, but here's my problem :


I recently (like 2 weeks ago) a brand new iMac 27 inches

 

iMac13,2

Intel Core i7 3,4 GHz

RAM 32 Go

NVIDIA GeForce GTX 680MX 2048 Mo

OS X 10.8.3

 

But my screen seems to have a problem with transparency, scrolling, full screen and other effects.

 

For example, if I press the "up" volume button, it will appear fine. But if I press it again before it disapears, it will flash weirdly.

 

Same thing happens if I put a video in full screen, my screen flashes weirdly for a millisecond, and then it's fine, but still it's not normal... I guess!

 

I tried to capture a video of the problem, but the bug doesn't appear on the video. Weird.

 

And just so you know, my eyes are fine!

 

Any of you guys have an idea what might be the problem?


iMac (27-inch, Late 2012), OS X Mountain Lion (10.8.3)
