On Fedora 23 with Gnome 3.18, I can reproduce all of the above bugs (2s stall while opening app tray, cursor framerate drop with fullscreen HexChat and Thunderbird, other random frame drops) in Wayland.

They do not reproduce in X with libinput. To be specific, the compositor still stalls heavily while opening the app tray, but the mouse cursor can still move while this happens.
