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. martin
