Image changes after free transform - Photoshop 2020 21.1.0

Hi there,

I'm having a problem that when I move an image or object with the free transform tool it slightly changes the image / object. See video in link. As you can see the circle changes on the right side (it becomes a little bit blurred) when the free transform is executed. Probably this is a setting, but I can't seem to find this (searched Google and this community).
