So I experienced an issue with my mbpr and wanted to share it with you all..... I had it for 2 weeks with no problem, then noticed some odd things happening when i would be using safari. It didn't matter if i was just checking my email or working on a website on Wordpress. I would experience random screen flashing and stuck browser windows when on safari.... Has anyone experienced this before? I have videos and pictures.... I took my mbpr to the Genius Bar and they deemed it a logic board issue with my graphics card.... They replaced it and i haven't experienced it again yet.... Here is the photos... ill work on uploading the videos.... Just thought i would share this with you all incase you were experiencing the same issue.
