I did some tests and research today: This is not a WM issue, it's
reproducible without any WM.

Meanwhile this issue is discussed in bug 7269 as focus follows
mouse (actually: mouse follows frame).  The workaround mentioned
by Anders Kaseorg in the discussion of the aforementioned bug is
to

M-x customize-save-variable focus-follows-mouse n.

This works for me.  

But I think the default value of this variable is surprising and
it's documentation does not explain that this actually leads to
mouse movements.

Ciao, Gregor
