>Description:

On a big endian machine the latest xf4 wm pkg is completely unusable.
It has serious issues on amd64 as well, but here it is no way
usable. Issues include:

 - dragging windows makes them randomly "snap" to borders not even
   near
 - does not stop dragging windows (seems to lose the lbutton up
   event)
 - click window content to raise window does not always work

>How-To-Repeat:
Try to use latest xfce4 on e.g. sparc64

>Fix:
n/a
