Reproducable with 97d6a786e0f9.

Looking at the problem more closely, it seems that the final rectangles
(after the theory has finished) are about half or maybe a third the size
of the rectangles during processes (and vanish, if they are small enough).

I made a short video:

I tested the Metal and Nimbus L&F; the font is IsabelleText. This is on
a system running Debian stable with Gnome 3.4.2.

I couldn't reproduce the behaviour on another machine with Debian
testing and Gnome 3.8.4.
