I'm a long time user of xdaliclock which I have "alwaysontop" with
a transparent background so it's always visible but hides very little.
Recently the author of xdaliclock decided to update the codebase to use
more "modern" techniques, so the transparency is not obtained using
X11's "nonrectangular windows" (IIRC it's an extension called "shape" or
something like that) support but instead it uses some kind of opacity
parameter intended for alpha-blending (so you can specify the percentage
of transparency).
Has anyone got Ctwm to support this kind of opacity?
