Output of evemu-record

If I touch the touchpad with more than 2 fingers at once and then move them around a little, X immediately crashes.

Appears related to #105160, but that issue was marked as fixed in 1.10.1, where this is still occurring.

There is more information that may be related at a downstream bug report: https://bugs.archlinux.org/task/57523

Output from evemu-record is attached. I also have a backtrace from Xorg.0.log:
