Question about windows borders and the default theme
I'm currently using Fedora Workstation 27 and I've noticed that there is a line between the window border and the window itself, and I don't like it. I can see it in the latest versions of Fedora, Debian and Ubuntu, but in Debian 8 this line didn't exist and I prefer it that way. Is there any wat to remove this line? I guess it's related to the gnome version and the default theme on each one.
This is how it looks on Debian 8: https://ibb.co/eUMuv6

Looking at screenshots, unfortunately, I am not quite sure what the issue is. Only thing I can see is that border is a bit darker on newer GNOME versions? If that's the case, you're right, that's likely due to version differences.
