When the client is resized, from gdk_wayland_window_update_size(), which

href="show_bug.cgi?id=773307">bug 773307</a> (which I used to investigate this one,
so I reckon both are the same issue)
Adding traces in gdk_window_impl_wayland_end_paint(), drop_cairo_surfaces(),
gdk_wayland_window_update_size(), and gdk_wayland_window_destroy() (the last
tow being the only caller of drop_cairo_surfaces()) shows:
gdk_wayland_window_update_size() window 0x1c473440 surface (nil)
drop_cairo_surfaces() window 0x1c473440 surface (nil)
gdk_wayland_window_update_size() window 0x1c473440 surface (nil)
drop_cairo_surfaces() window 0x1c473440 surface (nil)
