Help! Black bar on bottom of screen after long usage

[busyboi99]

Hi

It started out small when the black bar was covering my bottom screen especially after using a long period of time . usually a restart will do.
i woke up one day and that black thing covered most of my screen!

The top of my screen can still see my battery. what is this issue

i’m using mbp touchbar 2017

Welp, that doesn't seem right. I'd probably reach out to apple on this.

My first inclination is an app running causing this issue, but if it started off only a small percentage of the screen and suddenly "grew". Something is failing or had failed hardware wise - at least that's my thinking. If its easily reproduced then take it into apple had show them
