Processing is a Java application and has had troubles in my Awesome setup for a while now in various ways. With some early versions (2.x) the main IDE window didn’t want to redraw following a resize. Now with new IDE in 3.x series this problem is gone, but now the main output window thinks it has a window decoration and is offset in a very ugly way, showing a wide grey bar at the bottom and slighly less wide one on the right (lack of top window decoration and a scrollbar probably.
These problems can be solved with a program called wmname before starting a java application.

You can find it in the ‘suckless-tools’ package on Ubuntu/Debian.
It seems this needs to be run only once in one of the terminals and it then works accross any subsequent commands in the current session. Probably not stupid to put it in ~/.config/awesome/rc.lua?
