Features:

I created table.el table with Alt-x table-insert. Any text entered in

the table is invisible. The cursor moves forward but the text is not

seen. The problem occurs with or without org-mode.

This does not happen on an earlier versio of Emacs I use on another

machine, viz. Emacs 24.4.1, GTK+ version 3.14.9 of 2015-03-21

In GNU Emacs 24.5.1 (x86_64-unknown-linux-gnu, GTK+ Version 3.14.13)
