I can reproduce it without trying.  Unfortunately I do not know how
to reliably reproduce it.  It just happens very often.

Initially I blamed the decorators, but it happens with both
of them (so if it is decorator based it is in libdecoration).
The only difference is that kwd allows you to resize this window
but gwd doesn't.

This information was useful.  I do not use clone and I have disabled
all screen corners, the window seemed to disappear when I
restarted compiz, but it returned while I was typing this email.

Could it be related to the switcher?  I notice it comes and goes with
it sometimes and the window is around the area where the window title
appears on it.  It might be related to the switcher being switched
quickly.
