Actually, I am only updating the GUI right before I send the worker 
threads to sleep, mainly to save CPU time for the computation. I've been 
trying to fix this behavior with a pthread mutex that locks on GUI 
access but after reading the FAQ I think this only made it worse.

Thanks for the heads-up and sorry for asking FAQ-material.
