            Bug ID: 100042
           Summary: libinput handles mouse button remapping and button
                    scrolling in the wrong order
           Product: Wayland
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: libinput
          Assignee: wayland-bugs at lists.freedesktop.org
          Reporter: freeyourmind at gmail.com

libinput 1.6.2 (which isn't a choice in Version above)
xf86-input-libinput 0.24.0

With button scrolling enabled by running:

xinput set-prop DEVICE "libinput Scroll Method Enabled" 0 0 1
xinput set-prop DEVICE "libinput Button Scrolling Button" 3

xinput will synthesize scrolling events (buttons 4 5 6 and 7) when the
scrolling button is held down and the pointer is moved.

With the appropriate command to remap buttons:

xinput --set-button-map DEVICE 1 2 3 8 9 10 11

xinput can remap buttons, in this case 4, 5, 6 and 7 are remapped to 8, 9, 10
and 11.

Unfortunately, the button remapping happens *after* the synthetic presses from
button scrolling are created. If all the commands listed above are run, then
holding the scrolling button and moving the pointer produces events for buttons
8, 9, 10, 11. This makes it impossible to use button scrolling along with
remapping the physical buttons.

Evdev had the more preferable behavior of not remapping the synthetic events 
from its "Evdev Wheel Emulation", which allowed the physical 4, 5, 6 and 7
buttons to be mapped elsewhere while button scrolling could produce events for
4, 5, 6 and 7.
