For 12 months I have been having graphics card issues which all started on my 2011 MBP, which Apple replaced 12 months ago. I Then got a new shiny, 2013 highest end retina macbook pro from apple, in which after a couple of weeks had the exact same graphics issue. As soon as I start working in Premiere Pro with my 1080P DSLR footage, once the fans get up high, then the graphic colour hologram like start pooping on my screen. Now I got that retina replaced as I alerted apple about it, now they have given me the highest end 2014 model, and guess what? The problem is twice as bad.
I think it's definitely got something to do with the Apple software. It's weird though, because on the rare occasion, the graphic poop will show up on my screen when I am on Youtube (only once in a blue moon it does that) - it does it every single time 15-20 mins into editing with Premiere Pro, once the fans get hot. I can click on the graphics poop and it makes it disappear, which is weird, maybe that proves it software issue?
I don't know, but this problem has caused me to go through two of apples most powerful laptops, 60 phone calls to Apple, 1 investigation lodged to the Apple Engineers (the people who are above the Senior Apple Care Advisors) - Nothing seems to fix it, and I haven't been able to create any more intriguing films on my laptop because Premiere Pro CC just brings up all the graphics poop.
