Description

Created attachment 141809 scroll.evemu file that triggers journalctl errors

I'm trying to resolve a desktop crash that seems to be triggered by scrolling with my touchpad. Usually the touchpad scrolls fine, but once every few hours it'll crash my desktop environment (GNOME Shell) and return me to my login (GDM).

I found a core dump from GNOME Shell and opened an issue with more info: https://gitlab.gnome.org/GNOME/mutter/issues/327

But it looks like I'm also seeing libinput errors and bug report request, so I'm opening it here. Here are my local versions of everything related to libinput and Wayland:

local/libinput 1.12.0-2
    Input device management and event handling library
local/xf86-input-libinput 0.28.0-1 (xorg-drivers)
    Generic input driver for the X.Org server based on libinput
local/egl-wayland 1.1.0-1
    EGLStream-based Wayland external platform
local/libva 2.2.0-2
    Video Acceleration (VA) API for Linux
local/wayland 1.16.0-1
    A computer display server protocol
local/wayland-protocols 1.16-1
    Specifications of extended Wayland protocols
local/wlc 0.0.11-1
    Wayland Compositor Library
local/xorg-server-xwayland 1.20.1-1 (xorg)
    run X clients under wayland

This crash is happening under both X.Org and Wayland. I've attached an .evemu file as requested, please let me know if there's anything else I can do to help. Thanks!
