Wayland: fix up/down mix up in discrete events (from gtk-3-20 branch)) none

Description Joachim Frieben 2016-02-10 16:42:38 UTC 
Description of problem:
For a fully updated Fedora development (rawhide) system, choosing the (default) GNOME (on Wayland) host session has the effect that scrolling up- or downward with the mouse wheel in a virtual machine run in GNOME Boxes is inverted with respect to a GNOME on Xorg host session.

Version-Release number of selected component (if applicable):
gnome-shell-3.19.4-2.fc24

How reproducible:
Always

Steps to Reproduce:
1. Start GNOME on Wayland host session.
1. Run a Fedora 23 or 24 client session inside GNOME Boxes.
2. Scroll up- or downward with the mouse wheel in some GTK-based application like GNOME Terminal or Firefox inside the virtual machine.

Actual results:
Scrolling downward makes the scroll bar scroll upward and vice versa.

Expected results:
Scrolling downward makes the scroll bar scroll downward and vice versa.

Additional info:
- Choosing a GNOME on Xorg host session restores the customary behaviour.
- The type of the client session (GNOME on Wayland/Xorg) has no influence.

This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle.
Changing version to '24'.

I can confirm this is also happening on arch linux, also hapening when accessing the same qemu:///session with virt-manager and also happening when starting a KDE guest session.
Comment 3 Joachim Frieben 2016-05-03 18:58:16 UTC 
Issue is still present for gnome-shell-3.20.1-1.fc24. For the time being, enabling "natural scrolling" in gnome-control-center presents a workaround for restoring the correct direction.

Wayland: fix up/down mix up in discrete events (from gtk-3-20 branch))

Patch from https://github.com/GNOME/gtk/commit/a537bdc1fe4d4323b9a0c39b23cb15633eeff64c which fixes the inverse scroll direction of mouse-wheel events in a GNOME on Wayland host session.
Comment 6 Joachim Frieben 2016-05-04 11:23:18 UTC 
Issue is fixed upstream in the gtk-3-20 branch and will be included in the upcoming release gtk+ 3.20.4.
