X.org X11 Server Release 6.8
kormoc writes "The developers of X.org have just release the long-desired version 6.8.0. This release brings real translucency and allows one to set values on different windows. Also, nifty drop shadows as well as XDamage, an extention that limits redrawing of windows to only the areas that were damaged. The Xcomposite extention is still not stable, but it works well for some people. Why not give it a shot?"
Future enhancements to various window managers and applications should take advantage of these new X features. (xcompmgr and transset are clumsy utilities intended only for proof-of-concept.) For example, KDE's feature plan notes that true transparency has already been implemented in Konsole.
Runs shadows/transparency smoothly:
