Occasional horizontal purple line appearing for less than one second
My MBP would occasionally have a horizontal purple line appearing and disappearing for less than one second across the screen. The width is usually about 1 inch thick. It usually happens once or twice a day. Does anyone know if the problem comes from my screen or my GPU? Thank you!

You'll need to check things using an external monitor to be sure.
