FWIW, I get this on my XPS 13 DE (9360) with 4.11-rc1:

Just to confirm: I noticed "jumpiness during fine pointing motions" as
well since switching to 4.11-rc.

@benjamin: Just wondering: Could that have something to do with the
ps2->rmi handover? I noticed that patches to improve things in this area
are still circulating, which lead me to wonder if that might have
anything to do with this. But it's just a wild guess.

Same setup here. In case it matters: I'm running Gnome-Shell in Wayland
mode.

Ciao, Thorsten

P.S.: I fixed the model number in above quotes from Cameron to avoid
confusion (he has a 9343, and not a 9443, as initially stated; see a
different mail in this thread for details)
