I filed a bug with Fedora earlier on this problem.

Using Fedora 23 with xorg-x11-xserver 1.18.2, KDE plasma 5.19 on a Lenovo
Thinkpad 450s. The mouse/keyboard/display freezes for periods of 20-40 seconds
but if you wait long enough it starts until the next freeze. I get messages:
===========================
[  1120.069] (II) SYN_DROPPED event from "TPPS/2 IBM TrackPoint" - some input
events have been lost.
[  11[  1120.069] (II) SYN_DROPPED event from "TPPS/2 IBM TrackPoint" - some

============================

Yje problem I think actually exists with 1.18.1 as well but less evident. Here
is
my analysis:
xorg-x11-server-1.18.1-3, EGL interface, libinput-1.2.1-3 NO PROBLEMS

xorg-x11-server-1.18.1-3, glx interface, libinput-1.2.1-3 OCCASIONAL FREEZE

xorg-x11-server-1.18.2-1, either EGL or glx interface, FREQUENT FREEZE
