Severity: important
Dear Maintainer,
Since sometime in the GTK-3 series (it's been this way for a while,
so I do not remember exactly when it started), mouse wheel scrolling
has not been working.
I believe this is different from #716959, since it only seems to
discuss, mouse-wheel scrolling not working in content areas, while
still working with the pointer placed on the scrollbar itself, and
also seems to be limited to window-managers using the mouse-wheel to
switch workspaces. The problem I'm experiencing is that it isn't
working at all, and I don't have the mouse-wheel bound in the window
manager anyhow.
On the other hand, setting the GDK_CORE_DEVICE_EVENTS environment
variable to "1" makes the problem disappear.
I cannot say that I know the root cause for this problem, unfortunately.
There also seem to be several bugs related to mouse-wheel scrolling in
GTK 3 floating around the web, many of them seemingly confused with
each other, and I just happened to find this work-around without any
sources or reasons cited, at <https://bugs.archlinux.org/task/35348>.
(However, it seems to be confused with a bug in the Oxygen theme,
which I do not use.)
I'm having this problem both with the Testing and Unstable versions of
GTK3.
