Here is what my macbook desktop looks like: 'http://bit.ly/a0GtCl'
icons are also sometimes distorted on the dock too. as you can see from the picture, there are errors or weird graphics on icons or on the desktop itself. I have tried restarting my comp and waited several days but they come and go and are often different places on the screen, etc. Should I take it to Apple Genius??? Is it the logic board? (i just had a new one installed about 3 months ago.... THANKS!
You say that they just replace your board, i dont think that is the issue, you should start checking your video card.
Usually the lack of memory and the video card can cause this issues, be aware that if you have little memory ram you could face this issue,lack of memory in your video card will cause this.
