The list of surfaces used by weston_compositor_pick_surface() is maintained in list of surfaces stored on the compositor. This list is generated from the surfaces across all the layers using weston_compositor_build_surface_list. When destroying a surface the surface is "unmapped" with weston_surface_unmap which removes it from the layer list. However since the compositor surface list was only being rebuilt when the output was repainted a call to weston_compositor_pick_surface before the next output repaint would use an outdated surface list containing surfaces that have been partially destroyed. https://bugs.freedesktop.org/show_bug.cgi?id=65986 https://bugs.freedesktop.org/show_bug.cgi?id=66173 https://bugs.freedesktop.org/show_bug.cgi?id=66198
Weston Weston is the reference implementation of a Wayland compositor, and a useful compositor in its own right. Weston has various backends that lets it run on Linux kernel modesetting and evdev input as well as under X11. Weston ships with a few example clients, from simple clients that demonstrate certain aspects of the protocol to more complete clients and a simplistic toolkit. There is also a quite capable terminal emulator (weston-terminal) and an toy/example desktop shell. Finally, weston also provides integration with the Xorg server and can pull X clients into the Wayland desktop and act as a X window manager. Refer to http://wayland.freedesktop.org/building.html for buiding weston and its dependencies.
