I did some more tests. It seems that the curved bars are a feature of
something, probably Cairo. If I try to scroll with Thunar to the end
or beginning of a long list, I see the bars. This also happens with
Caja (the GTK3 Mate file manager), so the bars in themselves don't
seem to be a bug, or if they are it's a Cairo bug.

The bug in Ristretto and the one I came across in Thunar is that not
only one but two bars appeared in a static situation, when I was not
trying to scroll.

I made a 7 second video showing the feature in Thunar when I
repeatedly try to scroll past the beginning and end of a long list.
