(little) Graphic troubles - Ga z77 - any idea?

[jerbro]

hi everyone,

I've a very little issue on display, I'm sure it's nothing but I can't figure out where it comes from.

The installation of ML was done without too much trouble, the only problem remaining is somme flickering on safari (I've read this is a common problem / don't really mind).
What annoys me more (and seems to be a graphics problem of the same kind) is that I'm using logic X (audio software) and the playhead doesn't behave properly when I'm reading files.
It doesn't move although I can hear sound when I press play and jumps directly to another position when I press stop (meaning it moves and I can't see it!). Another odd fact: when I hover over, the pointer acts like the rubber in photoshop -> it "erases" the playhead!
Hope my explanations are clear enough. Everything here tells me it's a graphic related problem, some of the geniuses on this site might see where it comes from...

Anyway thanks for everything. My hackintosh is a real (uni)beast!
