I have this same issue, I bought the laptop just over a week ago and the first one had display issues where if you set it down on a certian angle the display flashes black and flickers until you move the laptop.
I sent that one back and recieved new one yesterday, it seemed okay after a few hours of use however the flickering started again this morning when i moved the laptop.
I dont know if its an issue with the software but it seems like a build issue. I will try usng the laptop for another couple of days to see if it gets worse, if it does I think I will return it for a refund as it seems like an issue with the laptops build.
