Instead of pictures, some kind of sepia on a macbook pro?

Question

Iron

Instead of a part of the pictures on any resource, sepia occasionally appears. What could be the problem?
macOS Sierra 10.12.4
MacBook Pro (Retina, 13-inch, Early 2015) - took less than half a year ago
What is it and what to do?

Answer 1

Check it out with another browser. If so with any, then rearrange the system to begin with, from scratch. Copy the data you need, format the disk, rearrange the system, install all updates, return the data.

Answer 2

I would suspect a graphics chip if you had it all the time, but you say that it is occasionally and, as I understand it, only on sites, i.e. there are no problems with photos, videos and other multimedia outside of sites.
Due to this, and due to the fact that this is a Macbook, it seems unlikely to me that there is a hardware problem. I had a problem with the graphics chip on my iPad about three years ago (after a strong blow), but there absolutely the entire screen image was striped, and you only have pictures in the browser.
