Everything desaturates to sepia-pinkish colour, but vertical lines in all colors appear over the whole screen and that lasts for anytime between a blink of an eye to several seconds.

It happens over and over at random intervals, and sometimes ten minutes would pass and it would start happening again. It would happen both when charging or just on battery. I’ve turned the laptop off and left it unplugged from a power source for now. Not sure what to do next.
