Run into the same problem, after several hibernation - wake-up cycles.
Discovered recently than this bug is interconnected with corruption of active
Xorg/Unity desktop GUI fonts family. In my case that was "Ubuntu*" fonts.
NEW FIX: works for the active user session, without loosing active
processes/apps:
need to switch all themes' fonts to other (Verdana, etc.) than the active font
set (Ubuntu *).
These are Default, Document, Monospace, Window header font.
One may accomplish this by using "unity-tweak-tool":
$ sudo apt install unity-tweak-tool
$ unity-tweak-tool
Open Fonts section ("abc" icon);
Change fonts;
Then refresh desktop, may need to restart some windows;
Also you may need to restart unity panel:
initctl restart unity-panel-service
Finding permanent fixes probably possible with fonts tweaking:
https://wiki.ubuntu.com/Fonts
Install alternative fonts, than do:
sudo fc-cache -f -v
However the bug could be related to runtime in-memory font cache
corruption, and installing the alternative fonts will do nothing with
the problem.
