This may not be relevant, but I've noticed that this mouse problem

https://lists.gnu.org/archive/html/emacs-devel/2016-04/msg00499.html

is now no longer present. I remember I didn't follow the suggestion in
the thread to bisect, so I'm unaware when it was fixed. I don't have the
problem now so perhaps Stephan's patch fixed that too.

Best wishes,
