I was seeing this in a patched version of dwm. Thanks for your
suggestion -the problem indeed seems to be window-manager related.

(dwm doesn't have a concept of iconification but) this is not getting
hit.  What is happening (I believe) is that the mouse pointer is getting
warped to the top right corner -- the window doesn't have any
decorations -- and emacs probably thinks it has lost focus, but the wm
keeps the focus on the window anyway.
