Description Marius Gedminas 2014-04-02 17:11:14 UTC 
I can make windows 50% translucent in gnome-shell if I run

    xprop -f _NET_WM_WINDOW_OPACITY 32c -set _NET_WM_WINDOW_OPACITY 0x7fffffff

and click on a window, but when I try the same with

    transset 0.5

nothing appears to change (and xprop doesn't show a _NET_WM_WINDOW_OPACITY property on that window).

Running transset -v prints

    Set Property to 0.75
    Property set on: 0x104ce00

which is different from the window ID shown by xwininfo.

I've also compared transset and xprop under xtrace and saw that transset is using the wrong window ID.

Looks like x11-apps/transset/dsimple.c (Get_Window_Under_Cursor) may need to be updated to do the recursive search for a window with the WM_STATE property that is done in, e.g., x11-utils/xprop/dsimple.c (Select_Window).
