gtk themes have bars over ui for example in gucharmap.

[Lyn Perrine]

To reproduce install xubuntu 15.10 and install and then reboot and open gucharmap with the default theme. Then scroll up and down with mouse and see opaque bars taking up screen realeastate in on gucharmap.

Description: Ubuntu Wily Werewolf (development branch)
Release: 15.10

I expected no bars and to have the window area for symbols in gucharmap exposed. Instead I got grey bars covering the screen.

[Simon Steinbeiß (ochosi)]

What you see is normal and expected. At least in your screenshot the scrollbars don't really hide stuff, it's just that the window is so small that not all of the content is visible.

On a more technical note: the scrollbars in Gtk3 apps have been set to be opaque for the time being. However, there's also a patch for our default theme Greybird that makes the new Gtk3 scrollbars nicer, so we might re-activate them.

So this bugreport is either invalid or fix committed.
