Showing missing letters in Gnome windows (emacs and gnome-calculator) while KDE windows (kcalc and okular) work.

Kubuntu 16.04 with kwin-x11 4:5.5.5-0ubuntu1, using nouveau drivers.

Some times (usually after some uptime) windows of Gnome programs will loose most of the characters, with only some visible. See attached screen shot.

I don't know where to start trouble shooting.

I'm sorry, but KWin is not the component at fault here. It is not 
responsible for the drawing in a window, it only sees the complete 
rendering result of the complete window.

My suggestion would be to try the proprietary NVIDIA driver.
