In https://debbugs.gnu.org/cgi/bugreport.cgi?bug=23074#38 I requested
some information necessary to understand what is going on and why.
Could you please provide that?

Also, I'm not sure I understand what systems are affected.  You didn't
provide the information collected by "M-x report-emacs-bug", so I
don't even know on what OS are you seeing this and in which Emacs
configuration.
