White stain on MacBook Pro 2017 Screen.
Dear Community, I've been using this MacBook Pro for around a year and a half now, it has been taken good care of, never fell or even been scratched or dented. I opened it today and noticed a white dash like spot on the right side of the screen, only visible off white background, as well as when you completely turn off the backlight and light this spot with your iPhone flashlight. I tried rubbing it away with a screen sponge but to no avail. Any ideas on what might have caused it?
