Hello there! I recently buyed an used macbook pro 2012 13 i5. But then i wake it up or closing and opening sceen, i see graphical artifcats, wihch are or a thick horizontal gray line, half of white screen with apple logo. Its happens only for a milisecond but im still woried. The strange thing is that i tested it in 3D benchmark, video (2k and 1080 60 fps), mac os and other apps...Everything with that was fine. So...Any ideas?
