The screen on my Late-2013 15" Macbook Pro is flickering. Like this: https://www.dropbox.com/s/gooh8epnzp8t1ii/IMG_0160.MOV?dl=0
It was replaced in December 2018 because of the delaminating problem, but that warranty is long gone.
Any chance this is a software issue? So far I have: reset SMC & NVRAM, tried booting in safe mode, and tried forcing the integrated and discrete graphics card. Anything else before I decide this is now a permanent clamshell computer hooked up to an external monitor?
