I am using emacs 24.5.1 on Ubuntu 16.04.  Sometimes parts= of the buffer become invisible.   For example, in the minibuffer the = part that represents the command and partial argument can become invisible,= such as c-x c-f failing to show  "Find file: " and the directory stri= ng.  In Perl I have found parts of the buffer that highlight different= components such as variable names or programming language words might also= become invisible, so the problem is not just about the minibuffer.  T= he problem does not go away when using 'emacs -Q'.  I used to use an o= lder version of Ubuntu that is no longer supported, and the problem started= appearing after I upgraded to 16.04.

Can you help me understand what is happening, and = what I might do to debug it?  I started looking at overlays and text p= roperties, but I still don't understand them well enough.    The = characters can be seen when I backspace over them.  I cannot predict w= hen the problem will occur, and the current remedy is to exit emacs and sta= rt again.
