Actually, this is a fullcreen issue, cause this crash phenomenon can be reproduced with resizor, weston-terminal, eventdemo and etc only by fullcreen and click.

The first bad commit is at Weston module:

    shell: Make the lock surface just a plain wl_surface too

Hello. I can't reproduce this issue. 

I have tried both in drm and X11 mode, tried several programs (dnd, terminal, eventdemo, clickdot) select Fulscreen from menu, etc. and nothing (all ok for me)

My versions

cairo:               1.12.2-106-g64d65f7
drm:                 libdrm-2.4.36-4-g8fad46b
glproto:             glproto-1.4.15-2-g458a9eb
libvpx:              v1.1.0-126-geab09e3
libxkbcommon:        2cb6c35
mesa:                snb-magic-10742-ge620f3e
pixman:              pixman-0.26.0-43-g4cdf8e9
wayland:             0.94.90-16-g8a02368
weston:              0.94.90-33-gdaf1aec
xf86-video-intel:    2.17.0-959-gf6f43a7
xserver:             xorg-server-1.12.2-92-gfc6979c

Thanks,

I tried also tried to reproduce this but could not. Can you possibly post
the 'bt full' for this crash?

I retried based on the version listed above and still got the bug reproduced.
btw. after you fullscreen clickdot, did you click in it? the crash happened only after click.
