It is very distracting to me. It usually is jerky causing me to look at it each time I scroll. It also takes a second for me to realize where I jumped to if I used page down, because I can not tell as easily where I am relative to where I was, visually. This is partly due to loss of relative distances but also because my eyes have momentarily followed the jerk. The only fixed that I can handle is a fixed background if there is a large difference in contrast between the page background and main content background. I hope this does not become a norm.
