Screen pixel problem weird pixels

In my opinion this is the same issue that was covered in this program:

https://www.apple.com/support/macbookpro...

But the class action law suit did not include the 13" machines, so Apple is not fessing up to the issue.

Your best bet may be to call Apple and request a "Flat Rate Repair". This will most likely entail replacing the logic board with the offending GPU. If a future law suit develops you would then be eligible for a refund from Apple, A Flat Rate repair usually runs $357 which includes shipping and taxes. It generally takes four days including shipping time. For that price Apple will repair any and all defects found and give you a sixty day warranty. To initiate this call 1-800-MYAPPLE has your serial number ready and a credit card.
