The major difference between this version and the previous is that kwin no longer forwards the opacity to the app window if it runs as a window window manager and a compositing manager. As Keith Packard said [1] > The window manager support is only needed to forward the property from the > application window to the frame; with the Composite extension, a > compositing manager can then take that value into account when > constructing the desktop image. Any X server can implement the Composite > extension; the one in the X server project at freedesktop.org is just one > such. It would be trivial to implement this extension in a direct FB > based X server, or any other X server which places windows in off-screen > images. There are a couple of reasons to do so: (a) simplifies code, (b) we don't temper with opacities on override-redirect windows.
