Something really Strange in the finder lateral bar (Lion)

[Izis]

Okay, I'm experiencing something really strange in my finder. And I'd like to know if it's an issue or if it's normal so please help me.

I'm talking about this :

I see some things like stripes here when the brightness is high.

Are you experiencing same issues ? Could you make a screenshot like me to see if I see the same thing ?

Stripes? I don't see any stripes on your screenshot, where exactly are they? I assume the gradient on the right side is from a window's shadow, right?

I don't see anything wrong with your screenshot, so it sounds like a display or display calibration issue.

Do you see stripes when viewing this page?

Nope, I'm on MacBook Pro. So I've no way to resolve this I guess ?
