Pretty early in this thread you stated

   Not reproducible here, but I'm not on GNU/Linux with GTK+.

and I proposed a fix to do on GNU/Linux what we do on Windows but Stefan
considered that too heavy because it sets a frame garbaged even when it
was only iconified for some short period and its contentes didn't change
at all.  So Stefan committed another fix for GNU/Linux and now proposes
to backport a similar fix to Windows.  And I can't tell much because the
semantics of "garbaged" are still eluding me.
