Ok ! keep us in touch, did you find more thread about this issue ?
Well that "fix" did nothing, the one from the apple community about changing the promotion to 60 hertz..did nothing, did no damage either, just made the flicker a split second if that was considered a change LOL..when yesterday it did not want to go back to the screen at all totally freaked me out, never happened before..but when it comes to this particular update I can honestly say Ive never experienced an update like this before with so many issues..I really hope this gets resolved in the next update, maybe in apples mind its no big deal, people can wait for a fix, its just a simple flicker, but I dont think having it flicker twice is good for the machine at least thats my opinion..so hoping for the best
