Comment # 19 on bug 943845 from Robert Schweikert

More than happy to provide additional information unfortunately I am also not
in a position from a time perspective to debug this. Consider it took me almost
2 month to supply the information for comment 5, which is a sad state of
affairs.

Anyway the desktop being used on the system is XFCE.

It runs emacs-gtk.

Hardware is a Lenovo Carbon X1 first generation, all Intel hardware
