Title sums it up. Every time i restart the bottom half of my screen shows pixelated red, green blue squares of different sizes and hues. This happens as the display is being turned off from the restart/power-off and started happening right after the High Sierra update. I live 2 hours from the nearest apple store and use it everyday for work so going into the store is a bit difficult. Is my Graphics card dying? I didn't find anyone else with a similar issue. I've had my mcbpro for about 4 months. :\
