Bug#726784: libgtk-3-0: Scrolling only works when window has focus

[Lukas Hofmann]

Package: libgtk-3-0
Version: 3.8.4-1
Severity: normal

Dear Maintainer,

in gtk2 programs I'm able to move the mouse pointer over a window and scroll
through it using the scroll wheel without the window having the focus. Programs
using gtk3 don't have this ability.
Example: When using Rhythmbox (gtk3) I have to move the focus to its window in
order to scroll through my music library. By contrast, I can scroll through the
file list in PCManFM (gtk2) even when a different window has the focus.
Since I'm using a dual-head setup, the behavior of gtk2 is much more useful in
my opinion and it would be nice if this was re-enabled in gtk3.
My window manager is IceWM, if that's relevant to the problem.
