Comment 21 for bug 1167079

I've been using overlay-scrollbars, bzr revision 391 (last to include GTK3 scrollbars) in Archlinux for a while.

I really prefer Ubuntu's design to Gnome's in the case of scrollbars. The Ayatana scrollbars allow for complete elimination of the trough and autohide when not in use. I also like that there are both gtk2 and gtk3 versions so this interface can be consistent between modern and legacy applications.

I'd like to get to the bottom of what went wrong and revive the gtk3 Ayatana scrollbar.

I've been banging my head on the wall over it for a while:

The glitches appear to be limited to GtkScrolledWindow, which shouldn't come as much of a surprise. What was the last version of gtk3 in which this didn't happen? 3.18.x?
