Hello All, I am a very new people on your forum but a few weeks ago i bought a new macbook pro retina with samsung panel. I haven't ghosting effect on my macbook but i have a new and really bad problem. I try to found a some information on Russians forums but nobody can help me with it. I can see an artifacts in the form of flashing pixels on all display. It occurs in 20-30 minutes after the start of work. Today i try to test it on game Dirt 2 and i can see defects after 2 minutes after start. So i think it can be reason with Geforce 650 but when i back to desktop and use HD 4000 i still see a problem. This is best seen on a black screen with high backlight. When i try to connect TV via HDMI i can't see any problem in my TV. So i really don't know what could be the reason. I attached the video with issue to video hosting http://vimple.ru/579f880e8b7045e09f8fc5bc097c5e2b Also i have a many software problem like Crashing safari and iTunes. It can be a few times per day. I really disappointed with my new Macbook. I haven't any problem with old 2009 Macbook pro with Snow Leopard but Mountain Lion is not working well.
