Metacity 2.34.1 does not appear to do so on my system. Dunno=20 about unity, not in a position to try it without excessive messing=20 about. Setting opacity on the client window absolutely does _work_ (i.e.=20 make the window translucent) under metacity with its compositing=20 enabled, but it doesn't actually propagate the window property as such.=20 i.e. If I disable metacity builtin compositing and use xcompmgr with=20 metacity instead, it's not picked up, which I checked in case xprop and=20 xwininfo -tree were lying to me (they apparently weren't). > Typical compsiting managers are separate programs from the window > manager (compiz for example), so they don't know what window is the > client window. Except they aren't anymore, most compositing managers you encounter=20 nowadays _are_ combined compositing/window managers e.g. kwin, xfwm4,=20 metacity. Also compiz: nowadays typically run as a sort of combined=20 (though multiprocess) compositing window manager with a "compiz window=20 decorator" rather than a separate true traditional wm. The gtk+ one=20 looks like metacity, uses metacity themes ...isn't metacity. And is=20 apparently non-reparenting =3D> no propagation involved anyway. I do understand the motivation for the propagation hack, but it's just=20 not what current versions of currently typical desktop env wms seem to=20 be doing (AFAICT on my debian/unstable system). Again, either way,=20 emacs blindly setting the property on its parent is the wrong thing. I=20 just suspect filing bugs upstream to window managers for the=20 non-propagation at this stage is something of a lost cause.
