Hello, I upgraded two days ago (snapshots 20180203 and 20180205 cumulated),
after reboot at GDM login screen or inside GNOME session under Wayland I can
only move cursor, I can't click and hovering an element doesn't do anything.

I'm aware of Mesa update plus cache cleaning (20180207) to fix SDDM white
screen issue but it doesn't solve my problem.

Of course I tried with other mice.

I don't have this issue under Xorg.

I see that snapshot 20180203 provided a Mutter update bringing a lot of input
changes, mostly about "touch" input, but could be related anyway.

The weird thing is that I don't see anyone reporting this issue in factory
mailing-list or Reddit for the moment, while SDDM issue was very discussed.
