Invisible scroll bars are a source of constant annoyance. And it sometimes takes me several attempts to move a window, because of all the various clickable things without visible boundaries. Frustrating.

On GNU/Linux run this command, it will fix it for all the GTK based desktops, such as XFCE, Gnome and Mate:

               gsettings set org.gnome.desktop.interface overlay-scrolling false
Under Mac you might have a similar Cocoa setting or whatever is called (nsproperties?) with "defaults write".

I'm on Windows and Mac. Not because I love them, but because that is where my customers are. Also I try to keep my computers fairly vanilla, so that they don't look too different to the user's computer when I do videos or screenshots of my software.

Windows: Settings -> Accessibility -> Always show scrollbars.

On Mac, the setting is also simply exposed in the normal “System Settings” app. “Appearance” → “Show scroll bars” → “Always”.
