Thanks for keeping an eye on such important details. Did you see this 
again in the meantime?  I could not reproduce it in the version 
f0d2609c4cdc nor in 97d6a786e0f9 from today.

Theory Orderings has very few warnings compared to Code_Generator or 
Ctr_Sugar, so there could be a problem with the GUI geometry calculations. 
These are just small rectangles painted in a certain spot -- when the 
theory is finished the odd messages move to the right and might just get 
out of view.

I've tried on Linux with Swing L&F Nimbus, GTK+, Metal, and it all works 
for me.

Do you have any special GUI or font properties?  If the problem still 
persists can you make a screenshot?
