I think so, yes.

See [1] et seq. for a discussion of what I think is the same problem, 
where the Cygwin X server doesn't notify X windows of a focus loss when 
the focus moves to a non-X window.

Unfortunately, my attempts at fixing this just introduced more problems 
(see [2],[3] et seq.), and so were reverted.
