Comment 8 for bug 1301472

While trying transset under compiz, even if the correct window is supplied directly by id,
it still insists to choose a different window.

I looked up the right window id for setting the property and used it for the --id option:

    $ transset -v --id 0x7d1bf3c 0.5
    Selecting window by id
    Selected 0x7d1bf3c, trying to get top parent ... found 0x1d56458
    Set Property to 0.5
    Property set on: 0x1d56458

0x7d1bf3c is the window with all the common properties like WM_CLASS
0x1d56458 did not have any window properties at all, and ended up having just the new one.
According to xwininfo -tree -root, 0x1d56458 is grandparent of 0x7d1bf3c.
