An addition to the X-window system which allows it to use the graphics
hardware more efficiently when doing things like displaying translucent
windows. Otherwise these things would be much slower and need a lot of
CPU time.

Run "X -version" from a terminal.

If you have an up-to-date Etch you have XOrg 6.8 already; XOrg 6.9 is
currently only in Sid. (KDE does not check for your XOrg version before
it displays the error message.)

Go to "K-Menu > Control Center > Desktop > Window Behavior >
Translucency" and uncheck the "Use translucency/shadows" box. If you are
new to Linux it is probably better to leave this feature alone for now.
