i have this problem too weird colors on my main menu and dock, same specs with JoshS182, 8 Days Old

I have the same issue with my 2011 iMac.... Hope we get a fix as it is quite ugly.

Did all of you have maybe beta iTunes installed? I noticed two days ago, that i was running iTunes when this colour distorsion happened.

nope, I didnt install beta iTunes, it just happen sometimes

I have the same issue on my 2011 iMac i5 with the HD 6970M 2GB…

Hopefully Apple addresses this issue. I will call Applecare.

Confirming that I have this issue too. It seems to crop up randomly. Today I was reading an article online and when I went to check my Dashboard, it had it, When I went back to my desktop everything was fine. Dashboard had this graphical issue though. A few days ago I had the problem on my external monitor and once on my primary built-in iMac monitor.

Again, I want to point out that I have the exact problem described with no deviation apart from it happening only on Dashboard too. The specs of my iMac are Core i7 Radeon HD 6970 2GB, 4GB of RAM.

for me not only dashboard main menu too ! huhu, can update fix this ?

I have the same issue here too..

It soo sad

when this happens by dash board background looks like its in 8 bit

I really hope they solve this quick

Strange enough I too am experiencing all of the same symptoms that everyone in this thread is experiencing... my macbook pro 13" (2009) hasn't had it happen.

but my 27" iMac Core i7 w/ AMD 6970M 2GB, 16GB RAM has this problem. it's happened 3 times. in the past 3 days. (twice today)

side note, my iMac also has kernel panicked twice first time having a kernel panic since OSX Tiger. :$

I also have a 27 in iMac Core i7 3.4 with the 2GB Graphics Card.

I called apple care and informed them + I recorded a video of it happening with ScreenFlow and sent it to apple. Please call apple care and inform them so they escalate this issue.

When I called them they sent me a file to Capture the Data of my computer to see what happened and what caused it.

By the way this computer should be able to connect with 6 screens simultaneously.

Please if you are experiencing this issue write here to inform apple about and call apple care or see the genius bar.

Thanks

most of us are AMD ATI 6970 2GB User, maybe this is our problem.

Not limited to the 2GB 6970m.

I have a 1GB 6970m installed in mine and I still get these isses
