Remove the weston_surface::blend attribute, which really meant that the texture produced valid alpha values. This was used to override the opaque region for RGBX surfaces, which produce undefined values for alpha. Instead, compile a new shader especially for RGBX surfaces, that hardcodes the sampled alpha as 1.0. Before "compositor: optimize/simplify shaders" there was a 'vec4 opaque' in the shaders, that would cause part of the texture to be forced to alpha=1.0. Now that is gone, and we need this replacement. To test: launch simple-shm, and use the super+alt+mousewheel combination to make it transparent. It should not show a light cross over the window.

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.
