Hello again,
Just updating this bug report with this exchange between the author and me:

What desktop or window manager do you use?
Do you use Compiz or another 3D effects? Try if switching it
off or on helps.
Actually I don't know what's the cause. When the traceback was printed
the program was repainting plots.
Generally painting is triggered from window manager (I think), maybe
it's triggered again and again, but I have no idea why it could
happen.
Thanks for your response. I use the default Debian testing gnome3
installation. I do not have compiz installed nor is there any 3D
effects active. However, gnome3's own composting (mutter) is enabled
(as far as I know it CANNOT be disabled).
I think you are correct. This repainting is being triggered
repeatedly. In fact, using top, to monitor the cpu usage when fityk is
running, reveals about 70% usage by fityk and more than 20% on Xorg.
I will try with a live image of debian testing including fityk,
but using another desktop environment devoid of any composting by
default like xfce.
I'm finally running an xfce desktop using Debian testing. The high cpu
usage of fityk GUI is gone. I'm positive no compositing is enabled or
any 3D effects. I think there's a connection here.
Not sure what to do about it now...
Andres
