Do they have window decorations?  On my system, my window manager does
this:

    $ xwininfo -tree

    xwininfo: Please select the window about which you
              would like information by clicking the
              mouse in that window.

    xwininfo: Window id: 0x10812b5 (has no name)

      Root window id: 0x1e3 (the root window) (has no name)
      Parent window id: 0x1e3 (the root window) (has no name)
         1 child:
         0x4200002 (has no name): ()  50x50+4+24  +292+59

    $ xwininfo -id 0x10812b5 | grep Class
      Visual Class: TrueColor
      Class: InputOutput

    $ xwininfo -id 0x4200002 | grep Class
      Visual Class: TrueColor
      Class: InputOnly


If I make it override-redirect, then it correctly hijacks mouse events without
displaying anything.
