I have removed the overlay scrollbars.
How can I configure GTK3 scrollbar clicking behavior?
GTK3 applications scrollbars behave strangely under Ubuntu 12.10 and 13.04. This also happens with Fedora 17 and 18.
When I left-click anywhere above or below the thumb, it jumps to that position and starts dragging from there. The expected behavior is to scroll one page up or down.
When I right-click anywhere above or below the thumb, it scrolls one page up or down. That is the behavior I expect from left-clicking, the same way it works on GTK2 and QT applications.
Horizontal scrollbars have the same problem.
This is very bad for consistency.
