Public bug reported:

Every once in a while, text will disappear. If you're wondering which
text, the answer is any text.  What I've typed in an office doc will be
invisible, but selectable.  Icon labels are invisible, but highlighted
when clicked.  Options in the control panel, and so on.  Rebooting takes
care of it, but it seems weird that it should happen.  I upgraded to
16.04 recently.  Also, I was playing around with a Linux Intel driver
for graphics, that might have interfered with something, but the problem
came up only recently.

I made some screen captures if anyone would like to see them.
