Green lines around windows 10 Instagram app videos

I get these green lines on the right and bottom of the videos when I use Instagram app of windows 10 to watch stories or the videos in the posts. I have reinstalled windows 10 just to exclude interference from other programs to no avail. Also I can't scroll the stories to the left or right. I can only watch the stories that fits on the screen which is about 10 icons. That means I can't scroll to see more people/icons. I do not have this problems when I use chrome with IG story extension.
