evemu recording from with libinput-1.10.0-2.fc27

When holding or moving a finger on touchpad, cursor jitters.

libinput-1.10.0-2.fc27

This does not happen with 1.8.2-1.fc27 at least, and didn't happen until a recent update to 1.10.0-2.fc27.

Laptop: Asus P53E

Additionally, it happens during two-finger scrolling.

And it doesn't happen for some time right after starting a session or when switching from a tty, but I don't really understand when/after what exactly it starts happening.

It happens both on Wayland and X11.
