So I bought the most expensive model recently: 15" retina, 512gb SSD, 16 gb ram, R9 M370X 2048 MB GPU & forcetouch. And I'm experiencing this issue: Every once in awhile the screen just shows static grey noise. It's not moving noise, just a flash. Altough this happens in a very short moment (like a blink), it happens about once an hour. I'm not sure what triggers it, but i'll like to hear, if anyone has experienced the same. I don't feel like this should be a problem on a 3000$ laptop. The Macbook is running with OS X Yosemite 10.10.4.
