<pre>I'm running Fedora 25 + GNOME 3.22 + Wayland on a 2016 HP Spectre x360 (Kaby
Lake).
With X, gnome-shell usually idles at 0-22% of one processor core and using the
trackpad barely increases this, if at all.
With Wayland, gnome-shell usually idles at 0-8% of one processor core and when
I use the trackpad, gnome-shell immediately spikes in CPU and memory usage.
Screen recording attached.
Note: the screen recording exacerbates the problem to a huge extent; when I'm
*not* recording, drawing circles with the trackpad spikes gnome-shell to about
30-40% of one processor core, and gnome-shell idles at 0-8%. When screen
recording, these increase to not 250% and 50%, respectively. But still, 30-40%
of one processor core seems very high for just moving the cursor around.
This seems to be a Wayland issue since it entirely disappears when logging into
an X session. I'm happy to collect any required information.</pre>
