I have a HP pavilion 23 windows 10 all-in-one and there is this wired pink tint on the left side, and with this is a ghost of a chat on google hangouts i had open at the time it appeared. i have litteraly no clue on the means of how to get rid of it, despite looking it up hundreds of times. please, help out some..? i know it's the screen because when i take a screenshot or something it doesn't pop up there. again, i need help and quick. it isn't my computer and i've been up for hours trying to figure out how to fix it.
