Be sure you're using FCP X 10.0.8.
How much RAM out of curiosity?
What is the format/codec of the clips you're editiing?
I'd also consider have that iMac checked out at an Apple Store. FCP X works your GPU harder than your other apps by far, I'd bet. Thus it will push it to show flaws more quickly.

Thank you for you answer.
I have 12 GB Memory and Final Cut Pro X was working properly until now.
The problem occure already at the preview windows, as soon as I close Final cut the graphic background looks good again.
I found that I have a similar problem also with iMovie, so I think it is maybe a hardware and not a software problem.
The hardware test does not show any problems, do you know another method to test the graphic card?
