    Hello,

    I need some help. I have a 2012 MBP 15" retina screen that shows a black screen delay then a garbled/scrambled grey screen for a split second before showing my desktop. This only happens from deep sleep, when waking the sleep from like 4 hours.

    I am not sure if this is potentially related to the Nvidia graphics issue or not. The laptop works fine otherwise.

    Here is a video demonstrating the issue:

    My 2012 15" rMBP has done that since 10.10.3, I figured its some bug to do with graphics switching on wake as everything else works fine otherwise. My identical spec far more used and abused 2012 15" cMBP has not ever exhibited the same issue.

    I ran the Apple Diagnostics test and it passes also. My screen is an LG screen and the screen retention is pretty bad :(

    Doesn't matter. Apple has other diagnostic software which us common mortals do not have access to that tests beyond what ASD does.

    Back during the 8600GT days, mine would pass every test with flying colours, and would exhibit no symptoms apart from random kernel panics that were not frequent at all.

    Apple plugged in their own test and it failed from the getgo. Logicboard replacement ensued.
