Sorry if this turns out to be just a problem with my build, but
kde-window-decorator is not parsing its command-line options correctly here. For
$ kde-window-decorator --opacity 0.80
kde-window-decorator: Unexpected argument '0.80'.
If I put an "=" in the command line like this,
$ kde-window-decorator --opacity=0.80
then there program launches normally, but the opacity is not correctly set: it
is much too low. Indeed, there is no difference between "--opacity=0.80" and
"--opacity=0.0". I am using 0.3.7 checked out by git on 2007-01-11.
Sorry about the phenomenal bug spam, guys. Adding xorg-team@ to the QA contact so bugs don't get lost in future.
Is this still relevant?
Mass closure: This bug has been untouched for more than six years, and is not
