Like i posted earlier there a program name TG pro. You can run you processor fan manually so thats can warmup your computer and les 15 min. Instead put u computer next to. An heater or oven ! The battery can explode! Buy the program and solve that problem thats the only way i solve it
I have the same problem and it’s the retina display temp not the processor temp. If you record the flickering screen with quicktime then play it back when the screen has warmed up, no flicker!
My Acer Aspire V3-572G started doing this about 4 years ago after the fan failed while gaming. Didn’t really notice it for a while other than when It was really cold, because it heated up fast with no fan. Also, the GPU is further away from the heatsink than the CPU, so it got hotter quicker. Once I purchased a new fan a few years back the lines on the screen stayed for longer and longer because the fan was keeping the GPU cool. I use this computer for school and it is very annoying, as it lasts about half an hour, and when unplugged it uses less power to save battery = less heat.
from front and back a few seconds, warming lcd with hair dryer immediately results in fixage. i bet its a chemical issue, the white flickery in winter i come across. because one night i forgot laptop under -5, -10°C in the car. ever since it becomes so.
