My screenshot image files look very weird when opening on photoshop

Hi,

I work with screenshots on photoshops a lot and from a couple of weeks I have noticed that when opening directly a .PNG or .JPG screenshot the image looks really distorted and saturated, when the original image or screenshot is not like that.

This is a sample of an original screenshot

And this is how Photoshop displays this same screenshot image, it even changes it if I zoom out and in of this image.

I can't find a logical explanation for this, it only does it with screenshots taking from my laptop.

I even uninstalled PS and updated it to the latest version and its not working.

Have you seen this issue before?

The solution I have found is to open that same image in illustrator and then copying to the clipboard to paste into a PS canvas, this is how it works but its annoying as I am not working with Vectors and have to keep both apps open.

I am using a macbook pro latest generation if this is useful to help explain the issue,

Thanks,

Aldo
