Description PatriceB 2013-10-23 05:57:52 UTC 
As described in title, I've noticed that .xbutton.subwindow field of the XEvent is always set to zero with emulated pointer events. According to  Peter Hutterer, it sounds like a bug : http://lists.x.org/archives/xorg/2013-October/056118.html
Comment 1 PatriceB 2013-10-23 06:26:25 UTC 
I've noticed also that:

* .xbutton.subwindow fild is correctly set in ButtonRelease emulated XEvent.

*  On XI_ButtonPress, (XIDeviceEvent*) cookie->data -> child is set to 0 and is correctly set on XI_ButtonRelease.
Comment 2 Olivier Fourdan 2015-01-02 10:06:09 UTC 
Can be reproduced using evemu, although, oddly enough, the same test performed in Xephyr does report the subwindow field correctly (i.e. don't try to reproduce using Xephyr).

I think both button press and motion events are affected, both report subwindow as none.
